Jetty is probably your best bet for an http proxy server in java: jetty.codehaus.org/jetty — Richard H

Why the need of building your own proxy server, there are enough products out there? — Kwebble

Use one of these instead http://proxies.xhaus.com/java/. Rolling your own proxy implementation will be much harder than you think once you've taken all the intricacies of HTTP into account.

there are many libraries which can you use.

for the A and B they can running hessian server(for listening) + client(for sending) and for the proxy server you can use JMS + hessian server + client same as for A and B. In this way you can send java objects.

But hessian is only on suggestion you can use RMI or spring remoting or maybe web services. By far which a have working hessian is the fastest and very easy to develop.

from 1 to 4 you ask how to design a application which is out of the scope and you need to do it by you self :).

I did something similar in my course project.

As far as i am concerned, the core knowledge u need to learn about java for this a proxy server is socket programming.

you can setup two sockets: one communicates between your proxy server and the web browser, the other communicates between your proxy server and the target server.

Also, you will need some knowledge about thread in Java, open one thread for each connection will be a efficient way.

And I assume that you already have the knowledge about those computer networking stuffs like http, tcp.etc.
