If you set the "free" address to a proxy server, you will find that you won't be required to enter the password when you visit the Web page. This is the "Free proxy server". Why would there be free? There are several situations:
1. Is a system loophole, once the network management found will be blocked;
2. Is a kind of network management and other people have the opportunity to approach the mainframe, the machine set up a proxy server;
3. Is the real kind-hearted person, is the machine as a free agent for the benefit of our colleagues. That's admirable! But the seizure was shut down fastest.
