mod_proxy

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

This module implements a proxy, gateway or cache for Apache. It implements proxying capability for 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 server. 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 have been added as well.[10]

As of Apache 2.4, mod_proxy_fcgi was also added, to proxy FastCGI requests to another server, superseding mod_fcgid and mod_fastcgi. [11]

gollark: Did you NEED to ask that in (almost) all the channels?
gollark: It's okay, but not recommended, because you will still be indirectly exposed to PHP.
gollark: PHP Hypertext Preprocessor bad because of large design flaws which, while partly resolved in newer versions, are still present in still fairly large numbers. And, subjectively, it looks really ugly.
gollark: <@151391317740486657> Did you know? PHP bad.
gollark: Yes, it's that.
