Abstract

Many secure tunnels require protocols that require special handling, authorization or security certificates, such as L2TP and PPTP. This often eliminates them for use between a corporate or agency network and outside, public networks. A secure socket tunnel protocol (SSTP) adds drivers in both the kernel and user mode to route standard protocol traffic, such as PPP, over a common HTTPS port. In the event of network interruptions, an exchange of a session cookie allows fast reconnection of the underlying HTTPS connection without affecting higher level applications.
