Apache reverse proxy.

[Bradley Marshall <bmarshal@PIsoftware.com>]

Hi BOFHs,

To set up an apache reverse proxy, there are 2 main ways of doing it.

1) mod_proxy
LoadModule proxy_module /usr/lib/apache/1.3/libproxy.so
ProxyPass        /path http://host:port
ProxyPassReverse /path http://host:port

2) mod_rewrite + mod_proxy
LoadModule proxy_module /usr/lib/apache/1.3/libproxy.so
LoadModule rewrite_module /usr/lib/apache/1.3/mod_rewrite.so
RewriteEngine on
RewriteRule   ^/path/(.+) http://host:port/$1 [P]
RewriteRule   ^/path  http://host:port/ [P]
ProxyPassReverse /path http://host:port

The first way seems to be the easiest if you only have simple
requirements, the second is more flexible as you can use mod_rewrite
to do more funky things.

This doesn't seem to work to webapps that don't know about the proxy
when you're doing HTTP POSTs, however.
