Description:

httptunnel creates a bidirectional virtual data path tunnelled in HTTP
requests. The HTTP requests can be sent via an 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.

httptunnel is written and maintained by Lars Brinkhoff. See the file
AUTHORS for more information about contributors to this package.
