On our Apache web server cluster, we have mod_pagespeed setup with memcached and domain sharding to cookieless domain.
Our web servers sits behind a loadbalancer with non-sticky sessions, and SSL offloading. With SSL offloading the loadbalancer requests web servers on regular http always, but sends the respective X-Forwarded headers. The Apache web servers are not configured for SSL/https.
Everything works great with mod_pagespeed for regular http, but not for https. Accessing website through https though:
- CSS gets tagged, combined and so forth
- JS does NOT get tagged and combined
- Some media (png, jpeg, gif) are tagged, some are not
- Resources are not directed to the sharded domains
I have attached my various configurations, note that mod_pagespeed is enabled on individual vhost - I have stripped non-relevant vhosts from the config below.
In the config below I have changed our primary domain to example.com and our cookieless domain to nocookie.com
