To allow pipelined ICAP servers. One web page could be streamed through virus-scan, content-filtering, and language translation servers, quickly. To support all 3 content encodings (content-length, chunked, and TCP-close) in HTTP 1.1. This replaced original store-and-forward protocol with continuous streaming of content through many servers at ...
The most common form of HTTP tunneling is the standardized HTTP CONNECT method. [1] [2] In this mechanism, the client asks an HTTP proxy server to forward the TCP connection to the desired destination. The server then proceeds to make the connection on behalf of the client.
Privoxy is a "privacy enhancing proxy", filtering web pages and removing advertisements. Privoxy can be customized by users, for both stand-alone systems and multi-user networks. [ 2 ] Privoxy can be chained to other proxies and is frequently used in combination with Squid among others and can be used to bypass Internet censorship .
An anonymous proxy server (sometimes called a web proxy) generally attempts to anonymize web surfing. Anonymizers may be differentiated into several varieties. The destination server (the server that ultimately satisfies the web request) receives requests from the anonymizing proxy server and thus does not receive information about the end user ...

The X-Forwarded-For (XFF) HTTP header field is a common method for identifying the originating IP address of a client connecting to a web server through an HTTP proxy or load balancer. The X-Forwarded-For HTTP request header was introduced by the Squid caching proxy server's developers. [citation needed]
A de facto standard for identifying the originating protocol of an HTTP request, since a reverse proxy (or a load balancer) may communicate with a web server using HTTP even if the request to the reverse proxy is HTTPS. An alternative form of the header (X-ProxyUser-Ip) is used by Google clients talking to Google servers.
Polipo is a discontinued lightweight caching and forwarding web proxy server. It has a wide variety of uses, from aiding security by filtering traffic; to caching web, DNS and other computer network lookups for a group of people sharing network resources; to speeding up a web server by caching repeated requests. It can be configured to use on ...
