HTTPort creates a transparent tunnel through a proxy server or firewall. This allows you to use all sorts of Internet software from behind the proxy. It bypasses HTTPS and HTTP proxies, transparent accelerators, and firewalls. It has a built-in SOCKS4 server. It supports strong traffic encryption, which makes proxy logging useless, and supports NTLM and other authentication schemes. Version 3.SN features privileged status and faster access for registered users.
Version 3.SNF adds a smarter retry feature, which makes HTTPort more resistant to proxy counter measures and the connections more stable.
