  • Method and apparatus for detecting and processing multiple additional requests from a single user at a server in a distributed data processing system
    Patent number: 6725252
    Abstract: A method and apparatus in a distributed data processing system for processing requests for documents. A request is received from a user for a selected page at a server. The selected page is returned to the user with a unique token, wherein each user is sent a unique token. Responsive to receiving a new request for a page, a determination is made as to whether the new request includes the unique token. Responsive to receiving the new request including the unique token, a determination is made as to whether a previous request from this user is simultaneously being processed by the server. Responsive to a new request having been received for a document while another prior request is pending, the new request is processed by either rejecting the new request, or by canceling the previous request and processing the new request, or by delaying the processing of the new request until the previous request has completed.
