For those of you who have been interested in the evolution of the Cached Dynamic Modules, here's the 3rd Incarnation. This article is written on the assumption that you are partly familiar with the Cached Dynamic Modules script. These first few pages go over the additions, and updates to the original code; then dives right into the (pretty) source code. The code should look familiar because a lot of the code used in this version has been used verbatim to the way Spencer set it forth in his article, Another Look At "Building Your Website With Cached Dynamic Modules". Thanks are due to both Spencer and JP for their initial work on the project.
