Abstract
A system, apparatus, and method are directed to converting from a use of a HTTPS connection to a tunnel connection while maintaining an underlying connection between a client and a server. An HTTPS connection is employed to establish a network connection between a client device and a network device. A gateway is selected to receive a request from the client device. In one embodiment, selecting may comprise using load-balancing, cookie-persistence, or the like. Subsequently, the HTTPS connection is transitioned to another application layer communication protocol connection. Transitioning may comprise converting from a use of a first protocol stack configured to process a HTTP connection to a second protocol stack configured to process a non-HTTP based application protocol connection, and establishing a tunnel between the client device and a server through the selected gateway.
