WP Super Cache is a plugin for more advanced WordPress users. Not that running the plugin is difficult, but the installation is a bit different than the typical plugin. If you’re not comfortable with tinkering around the insides of your Apache or PHP code, you will want to learn about that stuff first.
Poke around Apache.com, or better yet, read about Apache mod_rewrites in particular.

So, why is WP Super Cache so popular? Simply put, it will speed up your blog.
WP Super Cache creates a static html page and serves that up to visitors of your blog instead of the dynamic php pages. Visitors who are logged in to your blog, or who have left a comment, will see the dynamic php pages instead of the static, cached pages. By creating and using a static page that is cached the activity on your server will be reduced and it will run faster.
Installation Tips for WP Super Cache Plugin
- Assure that the Apache mod mime and mod rewrite modules are installed.
- WordPress fancy permalinks must be enabled.
- PHP safe mode should be disabled.
- Backup your .htaccess before installing the plugin.
- Upload the WP Super Cache folder to your plugins directory, where it will create a ‘wp-content/plugins/wp-super-cache/’ directory.
- Activate “WP Super Cache” on the WP plugins page.
- Go to Settings->WP Super Cache and enable caching.
- Visit the installation page for WP Super Cache to assure that the newly created .htaccess files – there are 2 of them! – were created properly.
In my case the .htaccess file in the root directory could not be modified as the permissions on that file were set as read-only. I had to manually add the lines of code from supercache to the existing .htaccess file. The second .htaccess file “wp-content/cache/.htaccess” was created correctly by supercache.
Now, after you’ve installed and activated the WP Super Cache plugin, when your blog gets really popular your server should be able to better handle the influx of new traffic.
