When WordPress users think of caching, WP Super Cache and W3 Total Cache generally spring to mind. These plugins have a combined 11.7 million downloads and are the go-to caching plugins for most of us. That’s not to say they’re perfect, though. In fact, all caching solutions suffer from one specific caching blind spot: caching pages for logged in WordPress users.
In March, Cache Buddy was released to address this problem. Developed by one of the WordPress platform’s lead developers, Mark Jaquith, Cache Buddy works alongside these established caching solutions to fix some of the most common caching problems.
A poorly configured caching plugin can do more harm than good, so it’s important to get the installation right.
