Response 500 on nonexistent domain

[Andrzej Kukula <An...@navopgd.pl>]

Hello.

I have set up caching proxy for my users. I've chosen 1.3.23's mod_proxy,
and set it up according to the example in the configuration file. Okay,
documents are cached, but I can't control access to the proxy using system
accounts. I tried two modules found in modules.apache.org, both of them
failed (mod_auth_sys didn't even compile, mod_auth_shadow doesn't by default
compile statically -- and I prefer not to use modules in caching httpd, and
I don't know what to do to force it to compile statically). So make me
sure -- probably the only thing is to prepare another password file with
just usernames and passwords extracted from /etc/shadow, and then have a
script to keep them in sync - it's crazy isn't it?

Another weird thing is when I enter some nonexistent domain into my browser,
I'm getting HTTP 500 response code. I turned on debug logging and saw
something like the following:

....

With httpd_2.0.28 things are even worse: everything works fine until I try
to enable disk cache :) Then I'm getting compilation errors...

Just tell me how to fix those things with 1.3.23? I use Mandrake Linux 8.1
on an i586, kernel 2.4.8. Usual sort of stuff...
