This plugin is a fork of a DB Cache plugin. Because his author did not updated its plugin to WordPress 2.8, I finally (after almost three months since release of WP 2.8) took his plugin and updated it so now it works with newest WordPress version. Additionally I fixed few bugs, cleaned up the code and make it more secure.
