This plugin generates static html files from your dynamic WordPress blog. After a html file is generated your webserver will serve that file instead of processing the comparatively heavier and more expensive WordPress 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. Static files are served to:
99% of your visitors will be served static html files. Those users who don't see the static files will still benefit because they will see different cached files that aren't quite as efficient but still better than uncached. This plugin will help your server cope with a front page appearance on digg.com or other social networking site.
If for some reason "supercaching" doesn't work on your server then don't worry. Caching will still be performed, but every request will require loading the PHP engine. In normal circumstances this isn't bad at all. Visitors to your site will notice no slowdown or difference. Supercache really comes into it's own if your server is underpowered, or you're experiencing heavy traffic. Super Cached html files will be served more quickly than PHP generated cached files but in every day use, the difference isn't noticeable.
The plugin serves cached files in 3 ways (ranked by speed):
If you're new to caching use PHP caching. It's easy to set up and very fast. Avoid legacy caching if you can.Recommended Settings
Advanced users will probably want to use mod_rewrite caching, but PHP caching is almost as good and recommended for everyone else. Enable the following:
Garbage collection is the act of cleaning up cache files that are out of date and stale. There's no correct value for the expiry time but a good starting point is 1800 seconds if you're not using legacy mode. If you are using that mode start with an expiry time of 600 seconds.
