A fast http, https, socks caching proxy server.
BS Editor: A fast http, https, socks caching proxy server.
Easy web based configuration, optional p2p anonymous mode.

If you dont want to install it, theres an online demo of the access configuration(not much else in the demo works)

Features:

* Easy Configuration
Web based, no editing text configuration files.
* Memory
No big databases are kept in memory, no matter how large the cache is, Memory Usage will only increase when more users access it at the same time.
* Speed
To see how much cpu the proxy uses, run top or Task Manager.
Then open multiple windows and hit reload continously, on my computer I usually run out of bandwidth before it goes near 3-5% cpu usage.
* Shared Cache
Can be used as a general cache for all users of a computer/network instead of one cache per profile.
* Automatic config
Auto generates the .pac file for automatic proxy settings, no more updating in the do not use proxy section of individual users browsers.
* Anonymous P2P proxy
Joining the anonymous proxy network will allow you to use other peoples proxys for browsing and allow them to use yours.
* SOCKS
Supports enough of SOCKS to run FTP, most Instant messengers, irc, LimeWire, etc.
* User authentication
Supports external user authentication. you can free download Anon Proxy Server 0.103 now.
