System and method for exposing synchronous web services as notification style web services

A computer program product for asynchronous processing of network communications between a client device and a respective synchronous web service, the computer program product comprising:

• a computer readable medium;
• a subscription module stored on the computer readable medium for receiving a subscription request and configured for processing the received subscription request to identify subscription request data in the subscription request for sending in a synchronous request message to the synchronous web service, to identify a notification filter expression in the subscription request for determining whether a synchronous response message received from the synchronous web service in response to the synchronous request message satisfies the subscription request data, and to identify a polling protocol in the subscription request for defining communication parameters of the respective synchronous request and response messages;
• wherein the polling protocol and the subscription request data are to be used in polling the synchronous web service.
