Tunnels a data stream in HTTP requests
Creates a bidirectional virtual data stream tunnelled in HTTP requests. The requests can be sent via a HTTP proxy if so desired.
This can be useful for users behind restrictive firewalls. If WWW access is allowed through a HTTP proxy, it's possible to use httptunnel and, say, telnet or PPP to connect to a computer outside the firewall.
