desproxy

tunnel TCP traffic through a HTTP proxy

Browsers (in general HTTP clients) use HTTP proxies to request web pages. The proxy forwards those request to the destination server. All the negotiation is done via the HTTP protocol, which is designed just to carry HTTP requests and no generic (TCP/IP) traffic. That is why you can't (normally) use Internet applications beside your browser if you are behind a HTTP proxy. That is what desproxy is good for. Desproxy is a TCP tunnel, which means desproxy can forward TCP/IP traffic via a HTTP proxy. Desproxy uses a HTTP/1.1 method (CONNECT) to establish TCP/IP connections on demand. CONNECT is used for SSL connections when accessing to secure sites. So if you can access sites that support SSL (www.hotmail.com for example) you can use desproxy.
