Polipo is a small and fast caching web proxy (a web cache, an HTTP proxy, a proxy server). While Polipo was designed to be used by one person or a small group of people, there is nothing that prevents it from being used by a larger group.

Polipo has some features that are, as far as I know, unique among currently available proxies:
1. Polipo will use HTTP/1.1 pipelining if it believes that the remote server supports it, whether the incoming requests are pipelined or come in simultaneously on multiple connections (this is more than the simple usage of persistent connections, which is done by e.g. Squid);
2. Polipo will cache the initial segment of an instance if the download has been interrupted, and, if necessary, complete it later using Range requests;
3. Polipo will upgrade client requests to HTTP/1.1 even if they come in as HTTP/1.0, and up- or downgrade server replies to the client's capabilities (this may involve conversion to or from the HTTP/1.1 chunked encoding);
4. Polipo has complete support for IPv6 (except for scoped (link-local) addresses).
5. Polipo can optionally use a technique known as Poor Man's Multiplexing to reduce latency even further.

The web is a wide-scale decentralised distributed hypertext system, something that's obviously impossible to achieve reliably. The web is a collection of resources which are identified by URLs, strings starting with
. At any point in time, a resource has a certain value, which is called an instance of the resource.
The fundamental protocol of the web is HTTP, a simple request/response protocol. With HTTP, a client can make a request for a resource to a server, and the server replies with an entity, which is an on-the-wire representation of an instance or of a fragment thereof.

A proxy is a program that acts as both a client and a server. It listens for client requests and forwards them to servers, and forwards the servers' replies to clients.
An HTTP proxy can optimise web traffic away by caching server replies, storing them in memory in case they are needed again. If a reply has been cached, a later client request may, under some conditions, be satisfied without going to the source again.
