-
- Anonymously surf news groups, chat rooms, and web sites!
-

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.

WebScarab for Eclipse is an extensible framework for analyzing applications that communicate using the HTTP protocol.
It includes an HTTP monitor and an HTTP proxy for recording all messages between your machine and remote servers.
It is a port to Eclipse of the WebScarab application from OWASP.
It consists of the following components:
Proxy: HTTP proxy that monitors HTTP communication.
Triggers: Eclipse extensions and user scripts that are executed on specific message patterns.
HTTP Summary View: Eclipse view that shows all recorded messages with the ability to save and edit the message content.
Main features:
- Tight integration with the Eclipse platform
- Easily create custom trigger scripts or trigger extensions
- Save and edit HTTP message content within the Eclipse environment
- View request and response message details
- Edit messages on the fly with manual triggers

RtspProxy is a proxy server for multimedia streaming services based on the RTSP protocol.
The current version is a complete rewrite from scratch in Java of previous versions based on C++. The goal is to build a robust and scalable system usable in production environment.
The proxy is based on an asynchronous network framework, Apache MINA , which is built on Java NIO. This framework does permit to RtspProxy to handle high loads and concurrent users.
RTSP Caching Proxy is a proxy server that works with the RTSP protocol in multimedia streaming reproduction. RTSP (Real Time Streaming Protocol) is an emerging protocol for "session initiation" scopes, its purpose is to establish the conditions of an audio-video streaming session. The streaming data is then sent over other channels using other protocol such as RTP (Real Time Protocol).
Using a RTSP proxy does permits to access multimedia content without the need of being directly connected to the internet, for example being behind a corporate firewall.
Enhancements:
- A preliminary implementation of the IP address and host name filter was added.
- The Windows startup script was fixed.
- Session data is properly cleared when a session is closed.
- Only a UDP port pair is used for all RTP/RTCP packet handling and sending for all the connected clients.

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.

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!
