Abstract:
1. A method, in a data processing system, for de-duplication in a Web services environment, the method comprising: responsive to receiving a signature for a portion of a request message from a client at a server machine, performing a query in a bit stream repository to determine whether the portion of the request message has been previously received; responsive to determining the portion of the request message has been previously received, retrieving the portion of the request message from the bit stream repository; notifying the client that the portion of the request message has been previously received such that the client does not send the portion of the request message; and responsive to determining that receipt of the entire request message is complete, composing the request message, using the portion of the request message and at least one other portion of the request message, and according to de-duplication policy information, and passing the request message to a server application, wherein the de-duplication policy information comprises a digital signature algorithm used to calculate the signature for the portion of the request message and a chunk algorithm used to decompose the request message into the portion of the request message and the at least one other portion of the request message.
