mod_proxy is an optional module for the Apache HTTP Server [1].

This module implements a proxy/gateway/cache for Apache. It implements proxying capability for or AJP13 (Apache JServ Protocol version 1.3), FTP, CONNECT (for SSL), HTTP/0.9, HTTP/1.0, and (since Apache 1.3.23) HTTP/1.1. The module can be configured to connect to other proxy modules for these and other protocols.

One powerful feature of Apache is flexible virtual hosting — multiple virtual hosts on a single machine. This is a convenient way to partition separate websites and applications. With mod_proxy it is possible to set various web framework based applications up as virtual hosts as well [2] [3] [4].

mod_proxy can help to improve LAMP security [5] or to strip SSL from HTTP requests [6].

History

This module was experimental in Apache 1.1.x [7].

As of Apache 1.2, mod_proxy stability was greatly improved [8].

Since Apache 2.0 proxy features are divided into several modules in addition to mod_proxy: mod_proxy_http, mod_proxy_ftp and mod_proxy_connect — moreover caching is provided by mod_cache and related modules [9].

Since Apache 2.2 mod_proxy_ajp and mod_proxy_balancer added too [10].
