Anon Proxy Server 0.99
Anon Proxy Server is a fast http, https, socks caching proxy server. more>>
Main 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.
Enhancements:
- The program now checks for errors in access configuration.
- Variable timeout values were added.
- Log rotation was fixed.
- Occasional crashes on a bad URL were fixed.
- The auto configuration .pac file was fixed, so it should work even if the proxys URL was not set properly.
- Anon proxy defaults to 3 keys now for more reliability.

IMAP Calendar Proxy 1.3
IMAP Calendar Proxy implements an HTTP proxy that converts HTTP PUT requests of vcalendar data. more>>
IMAP Calendar Proxy project can be used with Mozilla Sunbird/Calendar to allow storage of a calendar via IMAP.
There are many issues with the program in its current state. Consider it alpha quality, and you may lose calendar data if you use it. Its more of a proof of concept right now. Its rather slow if you have a large calendar.
Ideally IMAP support should be built into Mozilla. This is just a hack. Id like to hear any feedback on how it works. See the TODO file for features Id like to implement.
Sunbird can post calendars to a remote HTTP server via HTTP PUT and to
synchronize via a GET before a PUT. This proxy should run on the same system
you run Sunbird on. It makes a connection to an IMAP server and selects
a specified folder.
It then retrieves all calendar data from that server and caches it it memory. Any changed to the calendar are HTTP PUT to this proxy, and it determines what to do on the IMAP server (delete, change, add). Instead of posting the whole calendar back to the server, it only posts the differences.
If you run the proxy elsewhere on the network, you will not get any bandwidth
savings because the HTTP PUT and GET are still done over the network.

irc-proxy 0.4 Beta
Ircproxy is a transparent IRC content filtering application. more>>

Zaval Proxy Suite 1.0.0
The Zaval Proxy Suite is an easy-to-use solution that allows monitoring TCP-based protocols. more>>
The Zaval Proxy functions as a proxy and transfers data between the server and the client writing incoming and outgoing traffic into log files. So you can see these raw data as is.
On start the Zaval Proxy Suite goes through configuration file and creates the specified number of proxy servers and the shutdown server.
"Proxy server" is a server socket listening on the specified port. When the client is connected proxy connects to the target server and transfers data between them logging entire traffic. On each connection 2 files are created - xxx-input (request data from the client) and xxx-output (response data from the server). The "xxx" means here the sequential number of the connection for the proxy server. The traffic is logged into the separate directory for each proxy.
Shutdown server is needed to close all open connections correctly and close the program.
So, in the particular case you should specify address of proxy server in client application (web browser, for example) and address of the target server in the proxy configuration file. You can create any number of proxy servers that run at the same time, however, they should use different port numbers.
