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: Natural ≠ good, as they say.
gollark: Some classrooms have no/broken WiFi coverage for no apparent reason despite sometimes having access points *in them*, which is a problem since because something something COVID-19 teachers got laptops instead of using the NUCs in the classrooms.
gollark: Oh, and there seems to be an issue storing preferences so Edge will ask you to set it up again on every login.
gollark: Even when you actually log in it's unusable for a while more because Windows spends a while using 100% CPU for no apparent reason. You can hear the NUCs VRRRRRRRRing as loudly as they can.
