HTTPTunnel is a simple client/server application for creating an HTTP tunnel between two machines, optionally via a Web proxy. This tunnel can then be used to wrap arbitrary TCP socket traffic in HTTP, thus allowing communications even through a restrictive firewall that only allows outgoing HTTP connections.

The HTTPTunnel code is now based on a reusable HTTP tunneling library (libhttptun, included in this source archive). This release includes improvements for tunneling high bandwidth connections, plus the usual minor bugfixes.
