Abstract
The solution of the present invention provides systems and methods for preserving transport layer header options traversing network devices that terminate transport layer connections. The solution described herein provides a bi-directional intelligent proxying system by which a proxy client exchanges transport layer option information with a proxy server via an application layer protocol. The proxy server, which may be in the form of an appliance, re-injects the transport layer options received from the client into the appropriate network packets communicated on the intended network. Likewise, the proxying appliance can inform the proxy client of transport layer options received from the network, such as via a server. With this solution, devices that transmit control information, exchange communications or other functionality via transport layer options may continue to operate in conjunction with transport layer terminating devices.
