(1) pingback hostname will always be generated from the accessed domain, otherwise speed would get highly compromised
|
||||
(2) 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.
|

(3) nginx compatility means that if used with PHP Memcache (not Memcached!) extension, the created memcached entries that can be read and served directly from nginx, making the cache insanely fast. If used with APC or Memcached, this feature is not available (no APC module for nginx, compression incompatibility with Memcached), although, naturally, the cache modul is functional and working, but it will be done by PHP instead of nginx.

Short nginx example configuration is generated on the plugin settings page if Memcache is selected as cache type.
