Fast Full Page Cache, backend can be memcached or APC
|
||||||
|
|
||||||
|
|
||||||
|
== Description ==
|
||||||
|
WP-FFPC is a full page cache plugin for WordPress. It can use APC or a memcached server as backend.
|
||||||
|
PHP has two extension for communication with a memcached server, named Memcache and Memcached. The plugin can utilize both.
|
||||||
|
A special function is that when used with the Memcache extension it produces memcached entries that can be read and served directly from nginx, making the cache insanely fast.
|
||||||
|
|
||||||
|
The naming stands for Fast Full Page Cache.
|
||||||
|
|
||||||
|
If used in WordPress Network, the configuration will only be available for network admins at the network admin panel, and will be system-wide and will be applied for every blog.
|
||||||
|
|
||||||
|
Some parts were based on Hyper Cache plugin by Satollo (info@satollo.net).
|
||||||
|
|
||||||
|
|
||||||
|
= Usage =
|
||||||
|
Configure the plugin at the admin section
|
||||||
|
|
||||||
|
== Installation ==
|
||||||
|
1. Upload contents of `wp-ffpc.zip` to the `/wp-content/plugins/` directory
|
||||||
|
2. Activate the plugin through the `Plugins` menu in WordPress (please use network wide activation if used in a WordPress Network)
