Method, System and Program Product for Processing Requests

A method, system and program product comprises queuing a request. The request is transmitted to a server in which the server queues a response, determines if the request is out of sequence, transmits an acknowledgment and an out of order response, and transmits an executed response. Missing requests are retransmitted to the server in which the server asynchronously transmits executed responses. Executed responses are received and removed from the queuing. A response receipt confirmation is transmitted to the server in which the server removes queued responses and processing of requests in order of transmission and detection/retransmission of missing requests is enabled.
