Donncha O Caoimh, the main developer behind the WP Super Cache plugin, has updated the plugin to 0.9.9.7, primarily to include Content Delivery Network (CDN) support. You can download the new version on the WordPress Plugin Directory.
A CDN is a network of servers designed to hold, and serve up, copies of files to website visitors to improve bandwidth and download times. The files are downloaded from the server closest to the web visitor, rather than all visitors requesting from the same physical server.
Caoimh explains how the plugin’s new CDN support works in his post:
The update also includes bug fixes and recommended links for speeding up your site right within the plugin options panel.
WP Super Cache is a page caching plugin that has been in development for over two years. By caching pages visitors don’t require unnecessary database requests, sometimes speeding up a website dramatically.
