Polipo is a caching HTTP proxy which has modest resource needs.
It listens to requests for web pages from your browser and forwards them to web servers, and forwards the servers’ replies to your browser. In the process, it optimises and cleans up the network traffic. It is similar in spirit to WWWOFFLE, but the implementation techniques are more like the ones ones used by Squid.
Polipo aims at being a compliant HTTP/1.1 proxy. It should work with any web site that complies with either HTTP/1.1 or the older HTTP/1.0.
- HTTP 1.1, IPv4 & IPv6, traffic filtering and privacy-enhancement.
- Uses 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.
- Cache the initial segment of an instance if the download has been interrupted, and, if necessary, complete it later using Range requests.
- 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.
- Complete support for IPv6 (except for scoped (link-local) addresses).
- Use as a bridge between the IPv4 and IPv6 Internets.
- Can use a technique known as Poor Man’s Multiplexing to reduce latency.
- SOCKS 4 and SOCKS 5 protocol support.
- HTTPS proxying.
- Behaves as a transparent proxy.
- Run Polipo together with Privoxy or tor.
