After a html file is generated your webserver will serve that file instead of processing the comparatively heavier and more expensive Word Press PHP scripts.The static html files will be served to the vast majority of your users, but because a user’s details are displayed in the comment form after they leave a comment those requests are handled by the legacy caching engine.
For example, to disable these checks in APC, simply add configuration.
When disabling these checks, it will be up to the server administrators to ensure that the cache is cleared whenever any source files change.
This plugin will help your server cope with a front page appearance on or other social networking site.
If for some reason “supercaching” doesn’t work on your server then don’t worry.
If you remove a package from the cache, you do not affect the copy of the software installed on your system.
