Hi everyone,
We're running Apache HTTPD 1.3.33 on a Debian-stable server (although we
do have a server on 2.0.54 if that will make things easier), and I'm
attempting to set up a reverse proxy but keep running into trouble with
URL escapes.
A server on a nearby subnet is causing big problems for users on dialup
because it returns massive pages (250+ Kb), and several clients keep
timing out. It's not an Apache server, and I've been led to
believe that most of the code for it was written in 1998.
In order to alleviate this, I'm trying to set up a reverse proxy with
mod_gzip to compress the large pages down to a more manageable size
(initial tests indicate that they can be reduced by as much as 70%).
However, I'm running into a problem: the target server is broken in
several ways, one of which is not handling escaped URLs. When you log in,
you get dumped into a /server/~username/ directory, which Apache appears
to be calling as /server/%7Eusername/ - this returns the target server's
idea of a 404 ("There is nothing to see at this location.").
I've looked at mod_rewrite's unescape function, but I'm afraid I really
don't understand how it works.
Short of hacking the source and commenting out all the unescaping
functions, is there a way to get Apache to proxy the requests verbatim?
The relevant parts of my httpd.conf are below.
Thanks for any assistance,
David Adam
