How to configure WP Super Cache

First thing you need to do is install and activate WP Super Cache plugin. Upon activation, WP Super Cache will notify you that caching is not enabled on your website at the moment.

To enable cache, go to Settings » WP Super Cache. Under the Easy tab, turn Caching on and hit update status button.

Turning on Cache in WP Super Cache for WordPress

After turning on the cache, click on the test cache button to check if it is working. WP Super Cache will fetch your WordPress site twice and will compare the time stamps of both pages. If the both time stamps match then this means that caching is working on your site now.

WP Super Cache Advanced Set up
WP super cache is a powerful plugin, and it comes with many advance options. These options can further improve your site’s performance. To Set up WP Super Cache with advance options, go to Settings » WP Super Cache and click on Advanced tab.

Enable Caching
First check the box that says Cache hits to this website for quick access. Below that you will see three caching options. By default WP Super Cache uses PHP to serve cache files. However, using PHP to serve cache files can be resource intensive particularly on shared hosting environments. So we would like to recommend that you try using mod_rewrite to serve cache files. After that scroll down and hit the update status button to save these settings.

WP Super Cache will now show you a notification that mod_rewrite rules must be updated and possibly another notification about scheduling garbage collection. Scroll down the page, and you will see mod_rewrite rules that needs to be added. Click on Update Mod_Rewrite Rules button to update these rules. Once mod_rewrite rules are updated this section will turn green.

To resolve the notice about garbage collection, scroll down on the advance settings page to the Expiry Time & Garbage Collection section and set up a time and frequency for garbage collection of cached files on your server.
