HTTP Proxy Client is the small set of libraries and scripts, which provides transparent access to Internet via HTTP proxy for programs, which uses TCP/IP for communication.
The list of programs includes: telnet, ftp, licq, cvs, smth else? Project implements dynamic library, that can be preloaded before program run.
The library substitutes some system calls (connect(), gethostbyaddr(), gethostbyname()), with calls, which makes TCP/IP connection through HTTP proxy. This allows client programs behind HTTP proxy work with Internet without limitations.
At the moment tested on i386 Linux, i386/sparc Solaris.
Enhancements:
- While using dotted address, applications will attempt to connect regardless DNS lookup result.

IMAP Proxy server is a caching IMAP proxy server. It was written to compensate for webmail clients that are unable to maintain persistent connections to an IMAP server. Most webmail clients need to log in to an IMAP server for nearly every single transaction.

This behaviour can cause tragic performance problems on the IMAP server. imapproxy tries to deal with this problem by leaving server connections open for a short time after a webmail client logs out.

When the webmail client connects again, imapproxy will determine if theres a cached connection available and reuse it if possible.

How does imapproxy keep track of which server connection is for which user?

Upon the first successful login to the real IMAP server (through the proxy), imapproxy fills in a little record that contains the username, an md5 digital signature of the password and the server socket descriptor thats being used.

After you log out and then log back in again, imapproxy just has to find a record that matches your username and password. These records are stored in a hash table (with the username being the hash key) in memory, so the lookups are pretty fast.

Can IMAP Proxy support multiple backend servers?

If you want IMAP Proxy to be able to proxy to multiple backend IMAP servers, you can run multiple instances of IMAP Proxy and make sure each instance is looking at a different configuration file.

Before you do this, take a look at perdition which appears to have been designed with this specific task in mind.

Open Proxy Scanning Bot (formerly NeoBOPM) is a loadable module for the NeoStats IRC Services. Open Proxy Scanning Bot scans clients connecting to the IRC network for insecure proxies, and also looks up a DNS blacklist for previously registered insecure proxies.
It caches the results of scans to increase perfomance, and with multiple bots, can be configured for load balancing.
It currently supports Hybrid7, Unrealircd, LiquidIRCd, Bahamut, QuantumIRCd, MysticIRCd, NeoIRCd, and Ultimate, with support for other ircds planned.
Enhancements:
- The code was updated to support NeoStats 3.0 Alpha 3.
- The DNS blacklist code was split out to a new module, BLSB.
- Several issues regarding NeoStats consuming 100% CPU when using OPSB have also been corrected.
- gcc 4.0 support was fixed.

IMAP Calendar Proxy implements an HTTP proxy that converts HTTP PUT requests of vcalendar data to separate messages stored on an IMAP server.

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.

The Zaval Proxy Suite is an easy-to-use solution that allows monitoring TCP-based protocols, such as HTTP, NNTP and others. It is extremely useful in software development and can be used as a debug tool. Another area of appliance is multiple connections logging with proxy facilities. As soon as its a pure java solution it can be used almost everywhere.

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.

BlueCoat Control Center allows people with BlueCoat proxies to monitor their proxy infrastructure. BlueCoat Control Center utilizes Tcl, MySQL and PHP.

Advanced URLs are polled, and the data is presented back through PHP. Syslog and real-time access log data can also be used to show proxy utilization and alerts.
