I ran across a great cgi:perl script for running anonymous proxies. Its called CGIProxy. I have to find creative ways of getting around the different blocking mechanisms while I’m on more locked down networks. Having a little personal proxy running in a few places helps.
If you have trouble finding it, I’ve been successful locating builds through its alias: nph-proxy. There are some unsavory types running the code out there, so be cautious with what traffic you send through somebody else’s network/proxy.
Here is a link to the home page for the beta version: CGIProxy Beta.
Should be helpful while traveling across the globe.
