Abstract
A method of utilizing transport protocols to provide bidirectional web procedure calls is disclosed. A callback request included with a web procedure call provides a destination address and port on the requesting device to be utilized in a new connection for receiving the response from the receiving device. The utilization of a callback request included with a web procedure call enables a receiving device to terminate the original connection upon which it received the web procedure call while performing the requested procedure. In situations where the requested procedure takes an extended period of time or the receiving device is responding to a large number of requests, the ability to drop the original connection, perform the procedure, and respond to the requesting device via a new connection saves resources on the receiving device. Replies to the request are sent to the requesting device utilizing the destination address and port included as a parameter in the callback request. Access to the receiving device is increased as connections do not need to be held open.
