Method and apparatus for detecting and processing multiple additional requests from a single user at a server in a distributed data processing system

A method in a distributed data processing system for processing requests for documents, the method comprising the data processing system implemented steps of:

• receiving a request via hypertext transfer protocol from a client for a selected page at a server;
• returning the selected page to the client with a unique token, wherein each client is sent a unique token;
• responsive to receiving a current request for the page, determining whether the current request includes the unique token;
• responsive to receiving the current request including the unique token, determining whether a pending request is present for the document;
• and
• responsive to a pending request being present for the document, canceling the current request and processing only the pending request.

A method in a data processing system for processing requests for documents, the method comprising the data processing system implemented steps of:

• receiving a current request from a user;
• determining whether the current request includes a unique identifier;
• responsive to the current request including the unique identifier, determining whether a previous request from the user is being processed based on the unique identifier;
• and
• responsive to a determination that a previous request from the user is being processed, canceling of the current request.

A method in a data processing system for processing requests for documents, the method comprising the data processing system implemented steps of:

• receiving a current request for a web page from a user,
• determining whether the current request includes a unique identifier;
• responsive to the current request including the unique identifier, determining whether a previous request from the user is being processed based on the unique identifier;
• and
• responsive to a determination that a previous request from the user is being processed, canceling the current request.

A distributed data processing system comprising:

• a network;
• a plurality of clients connected to the network, wherein the plurality of clients generate requests for documents;
• and
• a server connected to the network, wherein the server has a number of modes of operation including:
• a first mode of operation in which the server monitors for a request for a document;
• a second mode of operation, responsive to receiving a request as a current request, in which the server determines whether the current request for the document includes a unique identifier;
• a third mode of operation, responsive to the current request for the document including the unique identifier, in which the server determines whether a pending request from the client is being processed based on the unique identifier;
• and
• a fourth mode of operation, responsive to a determination that a pending request from the client is being processed, in which the server cancels the current request.

A data processing system for processing requests for documents, the data processing system comprising:

• receiving means for receiving via hypertext transfer protocol a request from a client for a selected page at a server;
• returning means for returning the selected page to the client with a unique token, wherein each client is sent a unique token;
• first determining means, responsive to receiving a current request for the page, for determining whether the current request includes the unique token;
• second determining means, responsive to receiving the current request including the unique token, for determining whether a pending request is present for the document;
• and
• processing means, responsive to a pending request being present for the document, for canceling the current request and processing only the pending request.
