Does HAProxy need Apache

Hi,

I've just been reading about Rubyworks and HAProxy etc.

Does HAProxy take Apache right out of the loop or does it sit behind
Apache.

Sorry if this is a silly question but it is not imediatly apparent on
the Rubyworks site

Cheers
Giorgio

I'd sit it being apache ( or better yet Nginx ) so you can only proxy
off requests for rails and get Apache/Nginx to serve images etc.
