Apache HTTP Server Version 2.0
This document describes what a Multi-Processing Module is and how they are using by the Apache HTTP Server.
The Apache HTTP Server is designed to be a powerful and flexible web server that can work on a very wide variety of platforms in a range of different environments. Different platforms and different environments often require different features, or may have different ways of implementing the same feature most efficiently. Apache has always accommodated a wide variety of environments through its modular design. This design allows the webmaster to choose which features will be included in the server by selecting which modules to load either at compile-time or at run-time.
Apache 2.0 extends this modular design to the most basic functions of a web server. The server ships with a selection of Multi-Processing Modules (MPMs) which are responsible for HTTP/1.1 200 OK Date: Mon, 07 Jul 2025 05:56:41 GMT Server: Apache/2.0.42 (Win32) PHP/5.2.10 Content-Location: mpm.html.en Vary: negotiate,accept-language,accept-charset TCN: choice Accept-Ranges: bytes Content-Length: 6887 Keep-Alive: timeout=15, max=100 Connection: Keep-Alive Content-Type: text/html; charset=ISO-8859-1 Content-Language: en

Apache 2.0 extends this modular design to the most basic functions of a web server. The server ships with a selection of Multi-Processing Modules (MPMs) which are responsible for binding to network ports on the machine, accepting requests, and dispatching children to handle the requests.
Extending the modular design to this level of the server allows two important benefits:
