You don't have to make any special changes to your theme. We encourage you to make sure that your provider supports <acronym title="Hypertext Transfer Protocol">HTTP</acronym> compression as the benefit of having your static assets available from more than one <acronym title="Point of Presence">POP</acronym> alone is not enough.</p>

- W3 Total Cache improves the user experience of your blog by caching frequent operations, reducing the weight of various theme files and providing transparent content delivery network integration. The goal is to improve the user experience for the readers of your blog without having to change WordPress, your theme, your plugins or how you produce your content. When fully utilized, your blog will be able to sustain extremely high traffic spikes without requiring hardware upgrades or removing features or functionality from your theme.

31
- 1. Unzip and upload the plugin to your plugins directory (wp-content/plugins/) when done wp-content/plugins/w3-total-cache/ should exist. If you have WordPress MU you will need to install this in wp-content/mu-plugins/w3-total-cache/.
32
- 1. Locate and activate the plugin on the plugins page. Set the permisions of wp-content back to 755 (e.g.: # chmod 755 /var/www/vhosts/domain.com/httpdocs/wp-content/) and click through to the General Settings tab.
33
- 1. Select your caching preferences for page, database and minify. If memcached is used this will require you to confirm or modify the default settings and add any additional memcached servers you wish to use. To utilize APC and memcached + memcache installation guides have been provided for those with virtual dedicated or dedicated servers. For those in shared hosting environments, contact your provider to see if either of these are supported.

- 1. If you already have a content delivery network provider, proceed to the CDN Settings tab and populate the fields and set your preferences. If you're not running a version of WordPress with the Media Library feature, use the Media Library Import Tool to migrate your post images etc to appropriate locations. If you do not have a CDN provider, you can create and use a subdomain instead, e.g. subdomain.domain.com to improve server response, pipelining performance and progressive render.
35
- 1. On the Minify Settings tab all of the recommended settings are preset. Specify any CSS and JS files in the respective sections, view your site's HTML source and search for .css and .js files. In the case of JS files you can determine the type and location of the embedding using the drop down menu. Avoid the inclusion of packed or obfuscated JS files in this step.
