free/open source proxy server in java with support

Question

I am looking for a easy-to-configure Proxy server in Java, that is either free or opensource, and has the following features--

1. Support for IPv6.
2. Support for HTTPS
3. Addition/editing/deletion of users permitted to access the proxy server- through command line is a must, and if this can also be done through web forms that would be great.

Also, in connection with my query, I found one script named Muffin(http://muffin.doit.org/), but it is quite old...Will it take a lot of time to add IPv6 support to it?(I dont know what exactly has to be done to enable Muffin to support IPv6)- the last release date of Muffin is sometime in 2000!

Answer 1

Jetty is one solution. They have a proxy servlet and should support IPv6 and SSL.

Addition/editing/deletion of users permitted to access the proxy server- through command line is a must, and if this can also be done through web forms that would be great.

This you would have to program yourself. Here's some docs about username/password stuff for Jetty. Jetty has a password class which generates the auth lines for the realm file yourself. You could easily write a script for it.
