HTTP Tunnel1.4.0

HTTP Tunnel is a small application for tunnelling an arbitrary TCP socket connection over HTTP. It can be used, for example, to tunnel traffic out from behind a restrictive firewall that only allows outgoing HTTP web connections.

The basic idea is that you run an instance of the HTTP Tunnel application locally in 'client' mode, that then connects out to another instance that you run at the remote end of the tunnel in 'server' mode. You then connect to the local client end of the tunnel with the application whose traffic you wish to tunnel, and all communications are then wrapped in HTTP. The tunnel may also go via a HTTP proxy, either explicitly or transparently.

Since all tunneled traffic is routed via the HTTP Tunnel server, a further side effect of this tunneling is that the client also gains an extra layer of anonymity on the Internet. This is due to the HTTP Tunnel server acting as a proxy to the client, and thus making it appear that the clients traffic actually originates from the servers IP address.
