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.

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.

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.

Shrew Proxy/Filter is a tiny proxy built on WEBricks HTTPProxyServer, extended for both URL and content filtering. Shrew Proxy/Filter is designed to be small, simple to configure, and easy to install.

It is extremely small, lightweight, and works quite well. All blacklists (both URL and content) are plain text, so most published lists can be simply dropped in and used.

Spike Proxy is an open source HTTP proxy for finding security flaws in web sites.

SPIKE Proxy is part of the Spike Application Testing Suite and supports automated SQL injection detection, web site crawling, login form brute forcing, overflow detection, and directory traversal detection.

To Use:

python spkproxy.py [ optional port argument, 8080 is default ]
Then set up your browser to use that port for both HTTP and
HTTPS proxies.

Then watch the traffic go!

UProxy is a proxy for UDP protocols. UProxy was initially designed to allow users to play Unreal Tournament matches over the Internet on computers sharing a dial up connection.
UProxy could also be used by any client-server application that uses the UDP protocol and doesnt require clients to bind a fixed port. UProxy should run under Windows, Linux, or any OS which supports BSD sockets.
Initially UProxy has been designed to allow playing Unreal Tournament matches over Internet on computers connected by a LAN sharing a dial up connection, but it could be used to play other games (such as Quake) and by every program using a UDP protocol where clients dont have to bind a fixed port (not only games!).
The main reason why I did UProxy when udpproxy already exists, is because I tried to port udpproxy to Windows but it was so difficult that I decided to rewrite it from a scratch. As result, UProxy should compile (and work) under Windows, Linux and, probably, every OS supporting BSD sockets.
UProxy doesnt support all the features of udpproxy yet, even if it should not be difficult to add them. However UProxy is now pretty usable and I will wait before adding other features while Im not sure I really need it.
Usage:
uproxy localport serveraddress serverport
where
localport is the port the proxy will listen to for incoming client requests
serveraddress is the address of the server where the proxy will forward client requests
serverport is the port the server is listening to for incoming client requests
Example:
My computer has the address 172.16.2.1 on my LAN. It is connected to internet by a dial up connection. If I want to allow computers on my LAN to access the an in Internet server having address 123.123.123.123 running Unreal Tournament on port 9999 I have to run the following command on my computer
uproxy 7777 123.123.123.123 9999
then other computers on the LAN have to use the address 172.16.2.1 as server (Unreal Tournament uses UDP port 7777 by default) to reach the Unreal Tournament server 123.123.123.123 on port 9999.
Messages:
While running, UProxy prints bytes in/out statistics every 10 seconds.
When incomes a request from a new client a message is shown and 30 seconds after the last packet sent or received by the client the pseudo-connection is dropped and another message is shown.
Enhancements:
- Besides some cosmetic changes in the code, this release should fix an ugly bug affecting UProxy when used in a Unix-like operating system.

mod_proxy_pass_env module provides virtual transparency of environment variables
when using the mod_proxy as reverse-proxy.

This module convert frontend environment variables(header-variables) to the HTTP header of the PROXY request.
