Xitami will run straight out of the box with no configuration. However,
advanced users may want to modify Xitami's behaviour with respect to
security, CGI, logging, etc. Xitami reads a configuration file,
xitami.cfg to get information such as the logfile name and MIME
types. This is how the configuration files work:
- If no configuration file is present, Xitami will use internal defaults
for most values, including some basic MIME types. However a fuller list of
MIME types can come only from the config file.
- The configuration file must be in the current directory, or on the PATH.
- You can either modify the xitami.cfg file directly (not recommended) or
create a second file, defaults.cfg, and place modified values
there. This is an example of a defaults.cfg file:
[Server]
debug=1
- The name 'defaults.cfg' can itself be modified in xitami.cfg.
- Since the defaults.cfg file is not included in the Xitami distribution,
you will no longer lose customised configurations when you re-install the
web server.
- If you change the defaults.cfg file it will be automatically reloaded by
the server after a short delay (usually 60 seconds). If you did not create
defaults.cfg, Xitami will auto-reload the xitami.cfg file.
- Any command-line options (or control panel options for the GUI versions
of Xitami) override the options set in the configuration files.
In this document, configuration options are specified using the notation
section:keyword, for instance 'server:debug=1' for the file example
above.
The URL '/admin' will launch the WBA. This URL is password protected so
that it is inaccessible until you have specified a new password. To enable
the WBA you should modify xitami.aut and set a password for the [/admin]
URL. Note that xitami.aut is re-installed with each new version, so the
better long-term approach is to define a [Security]filename= option in
defaults.cfg.
The WBA can be used in conjunction with this HTML-based help text, as
regards the various config options. At any time you can, of course, modify
the config files by hand.
To disable the WBA, remove the xiadmin entry from the [WSX] section in
the xitami.cfg and default.cfg files.
A configuration file defines a series of sections, each containing
options. Comments are indicated by '#' at any point in the line. Blank lines
are ignored. Each option takes this form:
name=value
The option name is case insensitive. You can put spaces around
the '=' if wanted. The option value is case-sensitive and may be
enclosed in double quotes if necessary. To specify an empty value, use "".
For example:
form-prefix=""
You can put references to environment variables in the configuration file
values using this syntax: $(NAME). Note that the name must be in uppercase,
and that such references cannot be embedded.
Prior to version 2.4, Xitami used "_" and "-" interchangeably in the
config files; this is no longer the case, and Xitami uses "-" in all keys.
This section defines the configuration file as valid for Xitami. You
should not delete or modify this section.
This section defines general parameters for the web server:
- webpages
- Specifies the directory root where web pages are located.
This can be an absolute directory or a relative directory.
- Default: webpages (a subdirectory of the server working directory)
- cgi-bin
- Specifies the directory where CGI programs are located. This can be an
absolute directory (starting with '/' or '\', if you prefer) or a relative
directory (not starting with '/' or '\'). See the section on
CGI directories for more details.
- Default: cgi-bin (a subdirectory of the server working directory)
- cgi-url
- Specifies the string that Xitami uses to detect that a URL is
to be treated as a CGI. This value must start with '/', and can
consist of one or more paths. For instance: '/cgi', '/script',
'/scripts/cgi'. This string does not actually refer to a real disk
directory; it is translated into a real filename using the cgi-bin
option, and a heuristic - see CGI directories.
- Default: /cgi-bin.
- refresh
- Specifies the delay in seconds between each server refresh.
At each refresh, the server does a number of administrative tasks:
reload the configuration file if changed; reopen the file
xitami.aut in any case; cycle the log files if necessary.
The refresh rate has a minimum of 10 seconds, unless it is set to
0 in which case no refresh occurs at all. (This can be used to
determine if the refresh is causing sporadic problems.)
- Default: 60 seconds
- debug
- If 1, the server creates various debugging log files. The file
request.log contains every incoming request. The file 'debug.log' in
particular logs the processing of the requests. The file 'header.log'
contains every response sent back to the browser. Use this to debug a
virtual host configuration that gives problems, or to determine the cause of
a recurrent problem.
- Default:0 (zero)
- debug-dir
- Specifies a directory for debug log files.
Xitami interprets this value as an environment variable if possible,
else as a literal directory name. If you want it to refer only to a
directory name, end it in '/'.
- Default: debug.
- temp-dir
- Specifies a directory for temporary files. The server creates these to
pass information to and from CGI programs, and if debugging is enabled, you
may find that these accumulate. Xitami interprets this value as an
environment variable if possible, else as a literal directory name. If
you want it to refer only to a directory name, end it in '/'.
- Default: temp.
- log-dir
- Specifies the directory for log files. This option applies to all log
files that Xitami creates, except debug log files. You can leave this
option empty, and specify a full path name for each log file: this allows
you to put different log files where you like.
- Default: logs.
- header-dir
- Specifies the directory for header files. Header files contain custom
HTTP headers, used for all files of some type. For instance, you can ask
Xitami to output the HTTP header 'Cache-Control: no-cache' for all files
with the extension '.txt' by creating a file called 'header.txt' in this
directory, and containing the HTTP header line. Each header file matches
all files with the same extension.
- Default: logs.
- limit
- Specifies the maximum number of concurrent HTTP connections. On
systems that can handle lots of open sockets (e.g. Unix, OS/2, WinNT,
Win98), you may want to set this high. Xitami does not impose any
fixed limit. If you set this value to 0, it means 'no limit'.
- Default: 20 connections for Windows systems, no limit on others.
- background
- If 1, the server runs as a background process, on operating
systems that support this functionality. If 0, the server runs
as a foreground process. Background processes are detached from
their controlling terminal and must be halted by a system 'kill
process' request. Foreground processes send their output to the
controlling terminal and can be halted by an interrupt key (e.g.
Ctrl-C). Currently, only implemented on UNIX systems.
- Default: 0 (foreground)
- autostart
- If 1, the server will run even if it cannot open the HTTP port.
It will retry every 5 seconds until you stop the server (which must
be done manually if the HTTP service cannot start). The autostart
option applies both to the HTTP and the FTP service. This option
is useful for systems where the network is not initially active, but
comes 'up' after some action (e.g. dialing-up). Currently it is
implemented only in the 32-bit Windows version of Xitami, partly for
various boring technical reasons, but mostly because this is the only
platform that actually needs it.
- Default: 0 (will halt if it cannot open its HTTP port).
- recover
- If 1, the server will try to recover from fatal errors using an internal
crash recovery system. This currently only works under Windows. When this
option is 0, Xitami will show a fatal error message and (under Windows)
allow the web administrator to continue. When this option is 1, Xitami will
silently recover and continue working.
- Default: 0 (will halt and show a message).
- dirsort
- Specifies the sort order for directory listings. You can sort by
file name, extension, size, or modification date/time using any combination
of the letters 'n', 'x', 's', and 't'. For instance, dirsort=xnt will sort
by extension, then name, then time. To sort in reverse order, use capital
letters. For instance to show the most recent files first, use dirsort=T.
- Default: n (sort by name).
- advertize
- Specifies whether Xitami adds the line 'Powered by Xitami' at the end
of directory listings.
- Default: 1
- keep-alive
- If 1, Xitami will allow browsers that support the Keep-Alive
protocol to carry-out multiple requests on a single connection.
This can improve performance, especially on pages with very many
small files. If 0, the browser creates a new connection for
each HTTP request.
- Default: 1
- keep-alive-max
- A number greater than 1; Xitami will allow this many requests
on an 'alive' connection before closing it. Setting this to 1 has
the same effect as setting keep-alive to 0.
- Default: 25
- timeout
- A 'kept-alive' connection will last this long before Xitami closes
it. The timeout is specified in seconds. You can actually put
this value quite high if wanted: the cost of an open connection is
low and does not degrade the server performance. Anything more than
a minute or so is probably not worth it.
- Default: 30 seconds
- defaultn
- Specifies the default files. Up to 32 default files can be specified.
When the user specifies a URL without filename, the server searches the
directory for the default files, in order, from default1 to default32, until
a matching file is found or the default sequence ends. Note that Xitami
automatically looks for .html extensions if a .htm file is not found.
- Default: default1=index.htm default2=default.htm
- cache-defaults
- Normally, defaults pages are cached like any other. This means that if
the browser has already loaded the page, it will add a HTTP request header
'If-Modified-Since'. Xitami uses this date to determine whether to send the
page or not. In most cases, it is appropriate to leave this option enabled.
However, if you are developing several sites, you may find that the browser
shows the default page from one site when you look at another. You can
clear the browser cache and reload, but this is usually pretty tiresome.
So, disable this option, and Xitami will never cache defaults pages.
- error-header
- Specifies the text used to preface an HTTP error message. The
text may either be HTML, or a filename prefaced by '@'. If the text
comes from a file, Xitami will re-read this file each time it sends
an error response.
- Default: <HTML><TITLE>Error</TITLE>
<BODY><H1><B>
- error-footer
- Specifies the text used to end an HTTP error message. The
text may either be HTML, or a filename prefaced by '@'. If the text
comes from a file, Xitami will re-read this file each time it sends
an error response.
- Default:</B></H1></BODY></HTML>
- text-xxx
- Specifies the text used for a specific HTTP error code. The text may
either be HTML, or a filename prefaced by '@'. If the text comes from a
file, Xitami will re-read this file each time it sends an error response.
The text is always prefixed by the error header and suffixed by the error
footer. You can use this for error codes 4xx and 5xx. 2xx codes are not
errors, and 3xx codes are handled by the browser without displaying any text
that the server might send. To test a specific error, you can use the
special URL 'error?xxx'. For instance, to simulate a 402 error (Payment
Required), use a URL like this: 'http://127.0.0.1/error?402'. You can
simulate a 302 error (temporary redirection) using a URL like this:
'http://127.0.0.1/error?302:/somedir/somepage.htm'. The error codes returned
by Xitami are:
200 | Ok
|
201 | Created
|
202 | Accepted
|
203 | Partial information
|
204 | No response
|
301 | Moved
|
302 | Found
|
303 | Method
|
304 | Not modified
|
400 | Bad request
|
401 | Unauthorized
|
402 | Payment required
|
403 | Forbidden
|
404 | Not found
|
412 | Precondition failed
|
413 | Request entity too large
|
500 | Internal error
|
501 | Not implemented
|
502 | Service temporarily overloaded
|
- Default:HTTP/1.0 XXX:error text
- priority
- Specifies the server priority, on systems where this is possible
(currently only Windows NT and 95). 1=normal, 2=low, 3=high. You can set
the priority to 'low' for systems where the server should not interfere with
other processes. You can set the priority to 'high' for systems where the
server is the main process.
- ipaddress
- Specifies the IP address on which Xitami should open its HTTP
connection. If this is 0, Xitami will open its connection on all available
IP addresses. This is normally a Good Idea, since it makes configuration
much simpler on a multihomed system, and is completely correct on a
single-homed system (i.e. a system with just one IP address, which is pretty
common). If you have multiple IP addresses and want to run Xitami on just
one of these, you can specify it here using the standard dotted network
address format. This will effectively disable IP-based virtual hosting.
- Default: 0 (take any available IP address).
- portbase
- Defines the IP port base for the server. Add 80 to this to
calculate the actual port used for the HTTP service. For
example, to run the server on port 6080, define portbase
as 6000. We use a portbase in place of an absolute address so
that multiple protocols (e.g. the FTP server embedded into Xitami)
can be managed as one unit.
- Default: 0 (zero)
- portbasen
- Specifies one or more alternate portbases; if the primary HTTP port is
unavailable, will try portbase1, portbase2, etc. until a free port is found,
or no further alternate portbases are found.
- Default: no default.
- base-host
- Specifies the name of the configuration file used for the base virtual
host. You may need this option when you have virtual hosts that all inherit
values from defaults.cfg, but where the base host needs different values.
- Default: basehost.cfg
- hostname
- Specifies your fully-qualified domain name for the server. This name is
used whenever the server needs to redirect a request (e.g. for image maps).
You may want to provide this when configuring a virtual host. It is not
usually necessary on single-hosted systems.
- Default: the system hostname.
- defaults
- Specifies the name of the local configuration file. This file provides
the defaults that are used for all virtual hosts. Anything in the defaults
file overrides the contents of xitami.cfg.
- Default: defaults.cfg
This section lets you define multiple document roots. Each alias
specifies a name and a path. For example:
[Alias]
cdrom=G:\html
private/pub=i:\pub
private/doc=i:\docs\current
The alias name may contain '/'. It is not case sensitive. In A URL, the
alias comes at the start, e.g.:
http://127.0.0.1/cdrom/index.htm
There is no fixed limit to the number of aliases you can define.
However, if you define large numbers of aliases, Xitami will run slower.
An alias can refer to a file, including extension. In this case, the
file will act as a default file for that alias.
This section lets you define virtual hosts. A virtual host can
be specified in two ways: by IP address (if your system has multiple
IP addresses) or by name (if your system has multiple names). Each
entry in the [Virtual-Hosts] section defines one virtual host, like
this:
[Virtual-Hosts]
www.rnd.imatix.com=research.cfg
253.112.23.51=home.cfg
See the section on virtual hosts for more details.
This section is used to define filter programs. Filters are
programs that are run with the (usually) HTML file as input. You
can write filters in Perl, Awk, C, Rexx, or any other language that
can handle standard input/output streams. Filters are a little
like CGI programs, except that they are invoked whenever a certain
type of file is requested.
Each definition in this section consists of a file extension with a
leading dot and a command. The command may be with a full path, or without,
if the program is on the PATH. Xitami lets you run scripts directly under
OS/2 and Windows 95/NT, if you respect the header conventions noted in the
CGI section.
You can pass any type of input file to a filter program, with the
restriction that it must be a text file. Binary files will probably not work
under MS-DOS-like file systems. Under Unix there is no difference between
text and binary files.
This is an example of the [Filter] section:
[Filter]
.ssi=perlssi # Pass *.ssi to the Perlssi filter
This section controls the CGI protocol:
- enabled
- Allows you to disable CGI handling in one stroke. If this is 1, URLs
that translate to a CGI are allowed. If this is 0, URLs that translate to a
CGI are rejected with a code 501 (Not implemented).
- Default: 1 (CGI is enabled)
- workdir
- Defines the directory where CGI programs will run. The web server must
have write access to this directory. You can tell Xitami to always use the
script directory by specifying "-". (This is useful if you put scripts in
various subdirectories.) This option applies to filters too.
- Default: - (script directory)
- wildcard
- Defines whether the CGI URL indicator ('/cgi-bin') is allowed anywhere
in the URL, or only at the start. If 1, it is allowed anywhere in the URL.
If 0, it may come only at the start of the URL. Note that setting this to
1 opens a significant security hole, if you also allow people to FTP files
into the HTTP area. As soon as someone creates a directory called /cgi-bin,
they can upload, and execute, CGI programs. In some configurations this is
desirable. In other configurations (e.g. if you allow your users to upload
CGI scripts, or if you do not do FTP uploads into the HTTP space) it can be
desirable.
- Default: 0 (/cgi-bin matches only at the start of the URL).
- timeout
- The maximum time, in seconds, that a CGI program may run. This option
prevents looping CGI programs from blocking the server system for more than
a short period. However, you will want to tune it if you run exceptionally
slow CGIs, e.g. large database searches. (Which we do not recommend; you
should always aim for a response time of less than 2 seconds, and 5 seconds
for 'heavy' processing.) If you set this to zero, Xitami lets CGIs run for
an arbitrarily long time (actually one hour) before killing them.
- Default: 60
- monitor
- The frequency, in milliseconds, at which Xitami monitors the progress of
CGI programs. If you raise this time to 500, for example, Xitami will check
the CGI program's progress every 1/2 second. Anything less than 100 is not a
good idea, probably, since it will slow-down the server.
- Default: 200
- dirlist
- If 1, the server will generate a directory listing for any URL that
refers to a CGI directory not containing a default file. If 0, such accesses
result in a 403 Forbidden response.
- Default: 0 (listings are allowed)
- msdos-style
- If 1, CGI programs and scripts get all filenames passed through the
environment and on the command line in MS-DOS format (using backslashes);
otherwise they get filenames in Unix format (using forward slashes).
- Default: 0.
- debug
- If 1, the server creates files containing the CGI input and output
streams, called tmpxxxxx.cgi and tmpxxxxx.cgo. You can use
these to debug CGI programs' output.
- Default: 0 (no debugging output)
- stdio
- If 1, the server uses standard input/output streams to pass CGI input
and output data. This is suitable for languages such as C, Perl, etc. that
have access to stdin and stdout streams. When using languages that cannot
read from stdin or write to stdout, you must set this value to 0, and refer
to the CGI_STDIN and CGI_STDOUT environment variables.
- Default: 1 (use standard i/o streams).
- mixed-url
- If 1, allows images, HTML, and other files in the cgi-bin directory. The
CGI program can refer to these using relative addressing. If 0, such files
are not permitted. Note that in any case, executable files (such as Perl
scripts) are always executed, never downloaded.
- Default: 1 (non-executable files may be placed in /cgi-bin)
- errlog
- Specifies a filename for output of CGI program errors. A CGI program can
send error messages to the stderr stream; these are captured in this log
file.
- Default: Empty (no logging of CGI errors)
- environment
- If 1, the CGI program gets the full web server environment, including
values such as PATH. If 0, does not have access to such data. The
environment data can assist a hostile attack on the host system.
- Default: 1 (server environment is supplied)
- http-fields
- Defines whether the HTTP request header fields are passed to the CGI
program or not.
- Default: 1 (HTTP header fields are supplied)
- http-prefix
- Specifies the prefix used to identify HTTP header fields in the CGI
program environment. Note that this should be different from the
form-prefix, so that there is no chance of an overlap in field names. To
specify 'no prefix', use http-prefix="".
- Default: HTTP_
- form-fields
- If 1, the form data (coming from a GET or POST method) is supplied as
environment variables. This can be required by some CGI programs. However,
when large forms are used, this may cause the environment to be over-filled.
Since the form data is also available to the CGI program on its standard
input device, it can be useful to set this option to 0.
- Default: 1 (form data is included in environment)
- form-prefix
- Specifies the prefix used to identify form data fields in the CGI
program environment. To specify 'no prefix', use form-prefix="".
- Default: FORM_
- form-query
- If 1, the form data (coming from a POST method) is supplied as the
environment variable QUERY_STRING. If 0, this data is supplied as separate
environment variables, and on the standard input device but not as a
QUERY_STRING environment variable. Some CGI products (we know of Progress
Webspeed) will barf if this is turned-on, since they do not expect input in
both this string and on stdin.
- Default: 0 (form data is not included in QUERY_STRING)
This section is used to define specific CGI environment variables.
Each definition is taken literally and passed to the CGI program.
This can be useful when using virtual hosts. For example:
[CGI-Environment]
HOSTNAME=sales
This section lets you define multiple CGI program roots. Each alias
specifies a name and a path. For example:
[CGI-Alias]
demos=G:\site\demos
The alias name may contain '/'. It is not case sensitive. In A URL, the
alias comes at the start, e.g.:
http://127.0.0.1/demos/calendar
This section controls the LRWP (long-running web process) protocol.
- enabled
- Specifies whether the LRWP agent is enabled or not.
- Default: 1.
- port
- Specifies the port on which the LRWP agent accepts connections.
- Default: 81.
- webmask
- Specifies the webmask for LRWP clients. Normally this is restricted to
local LRWP clients, but you can also construct LRWP networks from multiple
servers. Use 'webmask=local' to specify just local addresses, or
'webmask=item,item,...' to specify one or more types of access. Each item
allows or excludes some IP address(es): '250.12.13.*' allows matching
addresses, '!250.12.13.*' excludes matching addresses (but does not allow
others). '!250.12.13.*,*' excludes one set of addresses and allows all
others. 'webmask=@iplist.txt' reads the list of webmasks from a text file.
More information is available.
- Default: local.
- allow-all
- Allows all LRWP clients to connect. If this is set to 1, any LRWP
application will be allowed to connect. Otherwise the LRWP-Application
section must be used to authorise specific applications, and optionally
specify a password to use during the authentication stage.
- Default: 1.
This section consists of one entry per application name (either URL
prefix, or a URL "extension" name). The entry should either to be set to
"*" to indicate the application is allowed without authentication, or to a
password/phrase that is used in LRWP 2.0 authentication with that
application. If a password/phrase is specified, then LRWP 1.0 clients will
not be allowed to connect with that name (as they cannot perform the
required authentication).
This is an example of enties in the [Lrwp-Application] section:
[LRWP-Application]
testapp=* # Connect without any password
secureapp=funky161 # Connect using secure password
This section defines HTTP server security options:
- filename
- Specifies the Basic Authentication file.
- Default: xitami.aut
- password-case
- If 1, passwords are case-sensitive. If 0, passwords are
always converted to lower-case before validation. If you set
this to 0, be sure to use lower-case passwords in the password
file.
- Default: 1 (case-sensitive)
- dirlist
- If 1, the server will generate a directory listing for any
URL that refers to a directory not containing a default file.
If 0, such accesses result in a 403 Forbidden response.
- Default: 1 (listings are allowed)
- admin
- If 1, the server will allow access to the web-based administration pages
(WBA). If 0, the WBA agent will not be started. This is a safe way to
disable WBA access, for sites where this is not needed and poses a potential
security hole.
- Default: 1 (WBA is enabled)
- superuser
- Specifies the Superuser password. If this is "" or "-", no superuser
access is allowed. Anything else is accepted as a password for all protected
resources, including the online administration functions. This password
overrides the webmask for any resource. So, be really careful.
Okay, I warned you. (It does not override the webmask for the entire
server.)
- Default: "" (disabled)
- safepaths
- If 1, the server will refuse access to 'unsafe' URLs, which is a notion
that Microsoft invented when they allowed the same file to have a short and
a long filename. When this is enabled, Xitami rejects any URLs that contain
a directory name which can be translated to a different long name and the
user receives a 403 error message. If 0, this check is not done.
- Default: 1 (security check is enabled)
- webmask
- Limits the set of clients that can connect to the server. This is meant
to provide an easy way of creating an internal web service. The web mask is
one or more patterns, each of which specifies some valid or excluded
addresses. A pattern is some IP address in string format, possibly with '*'
replacing part of the end of address. For instance, the pattern
'250.12.13.*' restricts access to clients with IP addresses starting with
'250.12.13'. If you start a pattern with '!', the pattern excludes all
clients with matching addresses. A pattern '*' matches all addresses. Use
spaces and/or commas to separate patterns. The option 'webmask=local' has
special meaning: it restricts access to the local system, whatever its IP
address. You can't use the word 'local' in a list of webmasks.
If you want to use the same webmask set in a number of places, or if you
have a long list of addresses, you can use '@filename' as the webmask. Enter
the webmasks in the specified file, using whitespace or blank lines freely.
If the webmask file is not present, Xitami displays an error message in its
log files, and acts as if the webmask was not defined at all.
Some examples:
webmask=local # grant access to local browsers only
webmask=192.* # grant access to addresses 192.* only
webmask=192.*,127.0.0.1 # 192.* and local host
webmask=!192.*,* # deny access to 192.* addresses
webmask=@iplist.txt # read webmask from a text file
- setuid
- Specifies whether the server switches to a safe user id and group at
startup. This only works under Unix systems. When you use this option, you
can be certain that the server runs with the minimum necessary privileges.
- Default: 0 (disabled)
- setuid-user
- When the security:setuid option is enabled, switches to this user id
after opening its HTTP and FTP ports. You should ensure that the user id
exists and has suitable authority to write to log files, etc.
- Default: nobody
- setuid-group
- When the security:setuid option is enabled, switches to this group id
after opening its HTTP and FTP ports. You should ensure that the group id
exists and has suitable authority to write to log files, etc. If you set
this option to an empty value, e.g. "", Xitami does not change the group id.
- Default: nogroup
This section controls the server error and information log:
- enabled
- Specifies whether server logging is enabled or not.
- Default: 1 (enabled).
- filename
- Specifies the name of the server log file. If this value is "NULL"
(spelling is important) then no log files are produced at all. This is
equivalent to running Xitami in console mode with the -q option.
- Default: xitami.log
- cycle
- Can be one of:
- startup, or 0 - cycle log when the server is starts;
- hourly, or 1 - cycle log each hour;
- daily, or 2 - cycle log each day;
- weekly, or 3 - cycle log each week;
- monthly, or 4 - cycle log each month, or
- manual, or 5 - manual cycling only.
- Default: daily.
This section controls the server access log:
- enabled
- Specifies whether access logging is enabled or not.
- Default: 1 (enabled).
- filename
- Specifies the name of the access log file.
- Default: access.log
- cycle
- Can be one of:
- startup, or 0 - cycle log when the server is starts;
- hourly, or 1 - cycle log each hour;
- daily, or 2 - cycle log each day;
- weekly, or 3 - cycle log each week;
- monthly, or 4 - cycle log each month, or
- manual, or 5 - manual cycling only.
- Default: daily.
- local
- Specifies whether to include local addresses or not.
- Default: 1 (include local addresses).
This section controls the server error log:
- enabled
- Specifies whether error logging is enabled or not.
- Default: 1 (enabled).
- filename
- Specifies the name of the error log file.
- Default: errors.log
- cycle
- Can be one of:
- startup, or 0 - cycle log when the server is starts;
- hourly, or 1 - cycle log each hour;
- daily, or 2 - cycle log each day;
- weekly, or 3 - cycle log each week;
- monthly, or 4 - cycle log each month, or
- manual, or 5 - manual cycling only.
- Default: daily.
- local
- Specifies whether to include local addresses or not.
- Default: 1 (include local addresses).
This section defines the configuration of the reverse-DNS lookups used by
Xitami to translate IP addresses for its access log files.
- primary-server
- Defines the primary DNS server used for lookups. This value is
mandatory for RDNS lookups.
- Default: 127.0.0.1.
- secondary server
- Defines a secondary DNS server, if one is available. This will provide
a backup RDNS server if the primary server does not respond.
- Default: "".
- recurse-lookups
- Specifies whether Xitami uses recursive lookups or not. Depending on
the DNS configuration, this can be faster or slower than non-recursive
lookups.
- Default: 1 (use recursive lookups).
- debug
- Specifies whether Xitami should output trace entries for its RDNS work.
If 1, each RDNS lookup sends trace information to debug.log. Use this if
you are having problems getting reverse-DNS lookups to work.
- Default: 0 (do not debug).
This section defines additional MIME file types; the following
MIME types are defined by default (if xitami.cfg is not present):
- default
- Defines default MIME type for file extensions that are not
otherwise defined.
- Default: */*
- txt
- Defines MIME type for files with extension .txt.
- Default: text/plain
- htm
- Defines MIME type for files with extension .htm.
- Default: text/html
- html
- Defines MIME type for files with extension .html.
- Default: text/html
- jpg
- Defines MIME type for files with extension .jpg.
- Default: image/jpeg
- jpeg
- Defines MIME type for files with extension .jpeg.
- Default: image/jpeg
- gif
- Defines MIME type for files with extension .gif.
- Default: image/gif
- doc
- Defines MIME type for files with extension .doc.
- Default: application/msword
You can add to, and modify, these definitions. Note that the extension
and MIME type must be specified in lowercase. To specify a MIME type for
files with no extension, use ".=xxx/xxx".
This section controls the browser-based admin screens.
- startup
- Specifies the initial screen to show; the values for this option
are deliberately not documented.
- Default: 1 (main page).
- refresh
- Specifies whether the console information screens should refresh
automatically or not. This only works with browsers that support the
<META HTTP-EQUIV="REFRESH"> tag. On some browsers, the refresh option
can cause warning messages.
- Default: 0 (refresh off).
- rate
- Specifies the rate at which the refresh occurs, in seconds.
- Default: 10 seconds.
- capture
- Specifies whether console output is sent to a file or not.
- Default: 1 (console output is captured).
- filename
- If the capture option is set, this option specifies a filename.
- Default: console.log.
- append
- if the capture option is set, this option controls whether the
console log is cleared each time the server is started, or not.
- Default: 0 (console.log is cleared each time).
- javascript
- If 1, the WBA screens will use small amounts of JavaScript to
improve the user-interface; for instance placing the cursor on the
first input field automatically. If 0, JavaScript will not be used.
In general enabling JavaScript will give better results.
- Default: 1 (use JavaScript).
- large-icons
- If 1, the WBA screens will show large icons on the icon bar. If
0, they will show small icons with only images, no text labels.
- Default: 1 (show large icons with text labels).
This section controls options specific to the 32-bit Windows
versions of Xitami.
- 16bit-cgi
- Defines whether 16-bit CGIs are supported or not. If they
are, all CGIs are run in a separate virtual machine. This is
safe but slow. If you use only 32-bit CGIs, you can run CGIs
faster by setting this option to 0.
- Default: 1 (support 16-bit CGIs)
- secure
- If 1, the 'Stop', 'Start', and 'Terminate' buttons on the Xitami Windows
control panel are disabled. This is intended for configurations where the
server may only be halted by an authorised administrator, using the WBA
control panel.
- Default: 0 (control panel is fully enabled)
- service-name
- This option is used under Windows NT for the NT service version of
Xitami. You can only change this by manually editing defaults.cfg; it is
not shown in the WBA. Change this before installing xiwinnt. You can use
this option to install multiple instances of Xitami each with a different
service name and title (as defined by the win32:service-text option). You
will need a separate working directory for each such Xitami service that you
start.
- Default: Xitami.
- service-text
- This option is used under Windows NT for the NT service version of
Xitami. You can only change this by manually editing defaults.cfg; it is
not shown in the WBA. Change this before installing xiwinnt.
- Default: Xitami Web Server.
This section is used to define web server extension (WSX) agents. A WSX
agent is written using the SMT toolkit. An example of a WSX agent is the
on-line administration agent. See the section on WSX development for
details. Each entry in this section defines a URL prefix and an agent name.
The prefix identifies all URLs passed to this agent, and consists of one or
more directory names separated by '/'. These are the standard WSX agents
that Xitami defines:
[WSX]
admin=xiadmin # Web-based administration agent "/admin"
error=xierror # Error simulation agent "/error?xxx"
You can modify this section if you want to add your own WSX agents, or
disable one of the standard agents. For example, to disable the on-line
administration feature, modify the above entry as follows:
[WSX]
admin=""
