[Xitami] xml file load error

[Toernooi Assistent]

after upgrading Xitami from 4d7 to 5b5, loading of an host xml file by an
html page with jscript (xmldom) stopped working. I keep getting client side
load errors. The xitami debug file suggests that the xxx.xml file is handled
OK. The error shows at the client side only (I think). This is what the
request log says on that particular file:

GET /opgaven/inschrijfForm.xml HTTP/1.1
Accept: */*
REFERER: http://localhost/maakform.html
Accept-Encoding: gzip, deflate
If-Modified-Since: Wed, 01 Aug 2001 15:02:32 GMT; length=3037
User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0)
Host: localhost
Connection: Keep-Alive
Cookie: fbestandsnaam=http://localhost/inschrijfform.xml

I reverted to 4d9 but still same result.
Thanks,
