WP Super Cache update brings CDN support, features and fixes


Donncha O Caoimh, the main developer behind the WP Super Cache plugin, has updated the plugin to, 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 CDN support simply rewrites images, CSS and Javascript files so they point at a different hostname. That hostname can be another virtual host on your own server (aka “Poor Man’s CDN”) pointing at your WordPress install or a fully fledged CDN. If your CDN supports “origin pull” then all the files on your server will be copied there as they are requested by visitors. Otherwise you’ll have to transfer the files over manually.

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.

Updates for WP Super Cache, Domain Mapping, Sitewide Tags, and Cookies for Comments Plugins


Donncha O Caoimh, WordPress Plugin developer and Automattic employee, updated his blog with fresh updates on his WordPress Plugins WP Super Cache, Domain Mapping, Sitewide Tags and Cookies for Comments.

Caoimh and Ron Rennick have updated Domain Mapping, the WordPress Multisite Plugin that allows for domains to be mapped to individual blogs on a network. In the most recent version, as Caoimh describes:

[The] new version … [includes] a new feature that allows you to ignore the “primary domain” on your blogs. It has the potential for duplicate content if a blog can be found at multiple domains but some people need this feature. With careful organisation of content this can be avoided.

The Multisite Plugin Sitewide Tags is almost ready for a new update, with added thumbnail support from Rennick, but Caoimh asks those who are able to test the development version.

WP Super Cache has been updated as well, with better preloading and more reliable homepage caching. Both Sitewide Tags and WP Super Cache will notify users through the Dashboard when the new versions are available.

Finally, Cookies for Comments has been updated by Caoimh as well. Cookies for Comments “sets a cookie on a random URL that is then checked when a comment is posted; if the cookie is missing the comment is marked as spam.”  The new update, as described by Caoimh:

I added code that keeps an eye on how long a visitor reads a post before they post a comment. If the comment is made faster than a certain time the comment is automatically caught. I’ve used it over the weekend here and elsewhere and it’s catching a good number of “real looking” but spammy comments!
