System and method for transacting a validated application session in a networked computing environment

DETAILED DESCRIPTION The present invention provides a system and method for validating a session request and transacting a communication session for a validated connection.
An intermediary receives a session request from a requesting client.
A SYN cookie is generated and a session is opened only if the SYN cookie is properly acknowledged by the requesting client.
A connection is initiated with a responding server and the session is transacted by translating sequence numbers by an offset reflecting the client versus the server sequence numbers.
The session is terminated upon the request of either the client or server.
An embodiment of the present invention is a system and method for transacting a validated application session in a networked computing environment.
A hierarchical protocol stack having a plurality of interfaced protocol layers is defined.
A connection-based session protocol layer is included.
A session is opened with a requesting client responsive to a request packet containing a source address of uncertain trustworthiness.
A client connection with the requesting client is negotiated.
A stateless validation of the source address contained in the request packet is performed using encoded information obtained from the request packet headers.
A server connection is negotiated with a responding server upon successful validation of the requesting client.
The session is facilitated by translating packets independently exchanged over the client connection and the server connection.
The session is closed through a controlled termination of each of the client connection and the server connection.
Still other embodiments of the present invention will become readily apparent to those skilled in the art from the following detailed description, wherein is described embodiments of the invention by way of illustrating the best mode contemplated for carrying out the invention.
As will be realized, the invention is capable of other and different embodiments and its several details are capable of modifications in various obvious respects, all without departing from the spirit and the scope of the present invention
