Summary

Warning

Do not enable proxying with ProxyRequests until you have secured your server. Open proxy servers are dangerous both to your network and to the Internet at large.

mod_proxy and related modules implement a proxy/gateway for Apache HTTP Server, supporting a number of popular protocols as well as several different load balancing algorithms. Third-party modules can add support for additional protocols and load balancing algorithms.

A set of modules must be loaded into the server to provide the necessary features. These modules can be included statically at build time or dynamically via the LoadModule directive). The set must include:

mod_proxy, which provides basic proxy capabilities
mod_proxy_balancer and one or more balancer modules if load balancing is required. (See mod_proxy_balancer for more information.)

one or more proxy scheme, or protocol, modules:

Protocol	Module
AJP13 (Apache JServe Protocol version 1.3)	`mod_proxy_ajp`
CONNECT (for SSL)	`mod_proxy_connect`
FastCGI	`mod_proxy_fcgi`
ftp	`mod_proxy_ftp`
HTTP/0.9, HTTP/1.0, and HTTP/1.1	`mod_proxy_http`
HTTP/2.0	`mod_proxy_http2`
SCGI	`mod_proxy_scgi`
UWSGI	`mod_proxy_uwsgi`
WS and WSS (Web-sockets)	`mod_proxy_wstunnel`

In addition, extended features are provided by other modules. Caching is provided by mod_cache and related modules. The ability to contact remote servers using the SSL/TLS protocol is provided by the SSLProxy* directives of mod_ssl. These additional modules will need to be loaded and configured to take advantage of these features.
