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.

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

Distributed computing environment (DCE) remote procedure calls (RPCs) are integrated with an advisory work load manager (WLM) to provide a way to intelligently dispatch RPC requests among the available application server processes. The routing decisions are made dynamically (for each RPC) based on interactions between the location broker and an advisory work load manager. Furthermore, when the system contains multiple coupled processors (tightly coupled within a single frame, or loosely coupled within a computing complex, a local area network (LAN) configuration, a distributed computing environment (DCE) cell, etc.), the invention extends to balance the processing of RPC requests and the associated client sessions across the coupled systems. Once a session is assigned to a given process, the invention also supports performance monitoring and reporting, dynamic system resource allocation for the RPC requests, and potentially any other benefits that may be available through the specific work load manager (WLM).
