Fast Full Page Cache, backend can be memcached or APC
Store WordPress pages in memcached and serve them with nginx - unbeatable speed!
== Description ==
WP-FFPC is a full page cache plugin for WordPress. It can use APC or a memcached server as backend.
The naming stands for Fast Full Page Cache.
PHP has two extension for communication with a memcached server, named Memcache and Memcached. The plugin can utilize both, however, the recommended is memcached.
WP-FFPC is a full page cache plugin for WordPress. Supports memcached server or APC as backend and both widely available PHP memcached modules, Memcache and Memcached as well.
= Features: =
* exclude possibility of home, feeds, archieves, pages, singles
* exclude possibilities: of home, feeds, archieves, pages, singles
* possibility to enable caching for logged-in users
* use APC or memcached as backend
* APC or memcached server storage
* 404 caching
* redirects caching
* Last Modified HTTP header compatibility with 304 responses
* shortlink HTTP header preservation
* pingback HTTP header preservation(1)
* fallback to no caching if any error or problem occurs
* syslog & debug settings available
* syslog & debug settings for troubleshooting
* supports multiple memcached backends
* Wordpress Network compatible(2)
* nginx compatible(3)
(1) pingback hostname will always be generated from the accessed domain, otherwise speed would get highly compromised
(2) If enabled as network-wide plugin in a WordPress Network, the configuration will only be available for network admins at the network admin panel, will be system-wide and will be applied for every blog.

(3) nginx compatility means that if used with PHP Memcache or PHP Memcached extension, the created memcached entries can be read and served directly from nginx, making the cache insanely fast.

If used with APC, this feature is not available (no APC module for nginx).
Short nginx example configuration is generated on the plugin settings page, under `nginx` tab.
NOTE: some features ( most of additional HTTP headers for example ) will not be available with this solution! ( yet )

Parts are based on [Hyper Cache](http://wordpress.org/extend/plugins/hyper-cache "Hyper Cache") plugin by Satollo (info@satollo.net).
== Installation ==
1. Upload contents of `wp-ffpc.zip` to the `/wp-content/plugins/` directory
2. Enable WordPress cache by adding `define('WP_CACHE',true);` in wp-config.php
3. Activate the plugin through the `Plugins` menu in WordPress (please use network wide activation if used in a WordPress Network)
4. Check the settings in `Settings` -> `wp-ffpc` menu in WordPress. For WordPress Network, please visit the Network Admin panel, the options will be available under Network Admin Settings page, in WP-FFPC menu entry.
3. Activate the plugin through the `Plugins` menu in WordPress ( site or Network wide )
4. Check the settings in `Settings` ( site or Network Admin, depending on activation wideness ) -> `WP-FFPC` menu in WordPress.
5. Save the settings. THIS STEP IS MANDATORY: without saving the settings, there will be no activated caching!
