Where on your system lives mod_xml2enc.h?

Maybe : http://httpd.apache.org/docs/2.2/caching.html#overview

(...)
This means that any other stages that might ordinarily happen in the process of serving a request -- for
example being handled by mod_proxy, or mod_rewrite -- won't happen. But then this is the point of caching
content in the first place.

Why? If you describe a bit more exactly what you are trying to achieve it
would help us help you.

You almost certainly don't want to configure your browser to use Apache as a
generic proxy.

Well, it's an invalid request. Port numbers don't belong in host headers.

I have a server that runs a web site. I also want that server to host
a squid http proxy for a different project - but squid has to be
listening on port 80 and so does the web server. So What I am trying
do do is send the request appropriately based on domain name. If is is
xyz.com then send it to the web site otherwise  chain it to squid.
Thanks,
David

Hi,

My previous replies have been rejected because tagged as spam ... hope this time it gets through ...

If you need your Apache reverse proxy as a frontend, you should have a look at
http://httpd.apache.org/docs/2.2/mod/mod_proxy.html#proxyremote as a forward proxy would be more
effective than a reverse, the latter only forwards requests to configured origin servers.
Last, but it seems ok in your config, this "forward proxy" setup should be used in the default vhost (the
first one listed).

Regards

Emmanuel

Do you want a forward proxy or reverse proxy? Based on your config, it
looks like you have it set up for reverse proxy. But if you're
configuring your browser to know about the proxy, then it's a forward
proxy. Not sure if this is the specific problem you're seeing, but I
think it will be eventually.

Hope that helps,
-Brian
