Abstract

A computing system in which a user of a client system can continue with submission of an additional request while an application framework processes prior requests. In an embodiment, when a request is received, the resource requirements for processing the request are determined. If the resource requirements exceed a threshold, the request may be processed in the background. The user can continue issuing additional requests. After completion of processing of a request, the availability of the results may be notified in a pre-specified portion of a window from which the user is interacting with the application framework. The user may conveniently request the results by clicking on a portion of the displayed message.

a server cluster containing one or more server systems, said server cluster to execute said application framework which receives said first request and said second request,

said server cluster to determine resource requirements for processing each request received from said client system, and to process requests requiring more resources in a background mode compared to requests requiring lesser resources in online mode, said service cluster determining to process said first request and said second request in online mode and in said background mode respectively based on determined corresponding resource requirements,

said server cluster to process said first request in an online mode to generate a first result and sending said first result to said client system for display on said first window,

wherein said server cluster sends a message to said client system indicating that said second request is being processed in said background mode upon the corresponding determination,

said server cluster to process said second request in a background mode to generate a second result, and to send a notification indicating availability of said second result of said second request for display in a second window also providing said user interface for said user to interact with said application framework,

wherein said client system displays said notification in a portion of said second window,

wherein said server cluster receives a follow-up request after sending said notification, wherein said server cluster sends said second result in response to said follow-up request,

wherein said message is sent prior to sending said notification.

2. The computing system of claim 1, wherein said server cluster generates a plurality of notifications corresponding to requests processed in said background mode and sends said plurality of notifications to said client system,

said client system displays said plurality of notifications in the form of a ticker in said portion of said second window.

3. The computing system of claim 2, wherein said server cluster sends said notification in the form of a hyperlinked text without including said second result, which when selected by a user in said portion at said client system causes a data to be sent to said server cluster, said data containing an identifier of said second result and requesting a response web page,

wherein said server cluster identifies said second result based on said identifier received from said client system,
