A multi-threaded proxy server under 500 lines of Java code.

• HTTP only.
• No keep-alive
• Opens a new connection to the target server every time a client connection requests for it.
• No caching.
• Supports UTF-8 URLs (not tested)
• Supports GET, POST and all other methods.
• Supports HTTP video streaming, for e.g., youtube.
• Supports logging of HTTP traffic from both client and server side.
• Supports reading of chunked transfer encoding. In the log files, even though Transfer-Encoding might specify "chunked", the data logged would have been decoded for convenience.

Feel free to modify the code for your own use.

But please acknowledge the original author. Thanks!

1. Build https://github.com/lucastan/java-utils
2. Make sure current directory is proxyServer
3. Put java-utils-xxx.jar you built in step 1 into the proxyServer/lib dir (create it if necessary)
4. Do git submodule init and git submodule update.
5. Do ant.

Command: java -jar dist-1.0.0/proxy-1.0.0-all.jar [options]

options:
-t : Number of threads. Default is 3
-s : No logging. Default is to log
-n : Number of listen back log [Default=20]
-p : Listen port [Required]

Example : java -jar dist-1.0.0/proxy-1.0.0-all.jar -p 8080 -t 5

Log files will be created as proxy.{thread-id}.{client/serv}.log For e.g., proxy.0.client.log stores all traffic received from the client.

The headers shown in the log files are in unmodified form, and might not be the exact headers sent to the client/server.
