[Xitami] Directory structure and proxy server

[xitami@lists.xitami.org]

OK boys and girls, here's a strange one (at least for me, I have never run
across this)

I had a user of this website (http://www.tahoecabinrentals.com) run into this
problem:
While trying to access the page http://www.tahoecabinrentals.com/cozycabin
they would get a proxy server error (and the page would not load) but if they
accessed it his way http://www.tahoecabinrentals.com/cozycabin/ (note trailing
slash) they are able to access the page (or any of the pages listed at the
site)

Also, I do noticed that when I enter the address into my browser without the
trailing slash, when the page loads the trailing slash is added automatically.

What's with that? Is that a proxy server issue or a browser issue?

FYI Running Xitami 2.5b4 under W2KPro SP2.
