Apache 2.0 - Available MPM's
Dated 15th January 2000
Apache 2.0 has a new architecture that moves the processing of requests from the code server into a MultiProcessing Module (MPM). By selecting the MPM to use you can alter the way the server behaves. Additionally the introduction of the MPM's has led to platforms developing their own optimised modules. On some platforms there is no choice, whilst on others there are different options, each with differing processing models. This list aims to help you select a suitable MPM for your system.
