Server request handlers

A method of operating a server comprising:

• receiving client service requests, each client service request including a handler identifier;
• selecting, for each client service request, a request handler corresponding to the handler identifier, the selected request handler processing the client service request by implementing a predefined procedure including:
• sending a handler service request to a destination server initially selected from a predetermined group of destination servers associated with the request handler;
• receiving a response message, including response data, from the initially selected destination server;
• and
• based on the response data, determining whether the pre-defined procedure is complete;
• and
• sending a reply message to the client if the pre-defined procedure is complete;
• and
• sending a new handler service request to a destination server newly selected from the predetermined group of destination servers if the pre-defined procedure is not complete.

A non-transitory computer-readable storage medium comprising computer-executable instructions executable by at least one processor to implement a server to:

• receive client service requests, each client service request including a handler identifier;
• select, for each client service request, a request handler corresponding to the handler identifier, the selected request handler processing the client service request by implementing a predefined procedure including to:
• send a handler service request to a destination server initially selected from a predetermined group of destination servers associated with the request handler;
• receive a response message, including response data, from the initially selected destination server;
• and
• based on the response data, determine whether the pre-defined procedure is complete;
• and
• send a reply message to the client if the pre-defined procedure is complete;
• and
• send a new handler service request to a destination server newly selected from the predetermined group of destination servers if the pre-defined procedure is not complete.
