Still new to all of this, so please bear with me
I’m currently using fastcgi + W3TC (I believe the former is for full page cache, the latter for object and database cache?)
Is redis also exclusively used for full page cache? Can I just switch out fastcgi for redis? Will W3TC still be required?
Also, why should I set it to ‘memcache’ instead of ‘Opcode: APC’ (from guide here: https://rtcamp.com/easyengine/docs/commands/site/ee-site-create/standard-wordpress-sites/#wordpress--fastcgi-cache) Btw, is that guide still up to date? Or did I miss a comprehensive setup tutorial on the plugins somewhere?
Also, I recently read this Cache Plugin Comparison: http://wpdevshed.com/best-wordpress-cache-plugin/. WP Super Cache seems to be the free winner. Would Redis + WP Super Cache be the best combination?
