I'm testing mod_pagespeed on a varnished powered server and wondering a couple things:
- How can I test to see that they are playing nice with one another?
- Can mod_page speed effectively replace Varnish?
Thanks for any insites.
Yes, they can play together.
Varnish is a reverse proxy and is able to handle a big number of requests and serves documents from it's cache. You have to allow caching in Apache's configuration (I use mod_expire for this).
Google's mod_pagespeed is able to optimize your content on demand. It doesn't change the stored files for a website, it modifies the files in the moment you are requesting them.
