I have a situation where I need to route requests to Apache through an internal Proxy Server before redirecting to an external Site, the setup is something like this:
Browser Request --> Apache --> Internal Proxy Server --> External Site
Without the Proxy Server I accomplished the redirect using a rewrite handled as a Proxy( [P] )
RewriteRule ^/somepath/(.*) http://www.externalsite.com/$1 [P,QSA,L]
I found setting up apache behind a forward proxy which looked like it was what I wanted to setup, and suggested I try the following directives:
ProxyPass /somepath/ http://www.externalsite.com/
ProxyPassReverse /somepath/ http://www.externalsite.com/
ProxyRemote http://www.externalsite.com/ http://internal.proxy.ip.addy:8080
When I set this up I got a 503 and the following Apache log entries:
[Thu Apr 11 07:47:14 2013] [debug] mod_proxy_http.c(1973): proxy: HTTP: serving URL http://www.externalsite.com/somefile.html

Nothing was logged in the proxy server logs, and I know the proxy server works if I set it explicitly in the browser and load that externalsite.com
Any thoughts?
