Description:

This module implements a proxy/gateway for Apache. It implements
proxying capability for FTP, CONNECT (for SSL), HTTP/0.9,
HTTP/1.0, and HTTP/1.1. The module can be configured to connect
to other proxy modules for these and other protocols.

This module was experimental in Apache 1.1.x. Improvements and
bugfixes were made in Apache v1.2.x and Apache v1.3.x, then the
module underwent a major overhaul for Apache v2.0. The protocol
support was upgraded to HTTP/1.1, and filter support was enabled.

Please note that the caching function present in mod_proxy up
to Apache v2.0.39 has been removed from mod_proxy and is
incorporated into a new module, mod_cache.
