# List of Apache modules

In computing, the Apache HTTP Server, an open-source HTTP server, comprises a small core for HTTP request/response processing and for Multi-Processing Modules (MPM) which dispatches data processing to threads or processes. Many additional modules (or "mods") are available to extend the core functionality for special purposes.
