The server that this script runs on simply acts as a medium that retrives resources for you. The only IP address shown will be the server's IP address. So basically, it is indirect browsing. The only catch being that the server has to has access to those otherwise inaccessible resources.

You simply supply a URL to the form and click Browse. The script then accesses that URL, and if it has any HTML contents, it modifies any tags that might contain URIs so that they point back to the script. You also have options of disabling JavaScript, accepting cookies, showing images, etc. that are available through the web interface.
