Abstract: Machines, systems and methods for processing a request in a client-server computing environment are provided. In one embodiment, the method comprises receiving from a client a request submitted to a server for purpose of synchronous processing by the server; assigning the request to a first thread for processing; registering the request with a request registration system, wherein the request is assigned to the first thread for processing, in response to determining that the request is acceptable and may be processed synchronously, wherein the request is unregistered from the request registration system, in response to determining that the first thread completed processing of the request within a first timeline, and wherein an alternative thread is assigned for processing the request asynchronously, in response to determining that the first thread did not complete processing of the request within the first timeline.
