Abstract: Embodiments of the present invention address deficiencies of the art in respect to managing interrupting requests to engage in a collaborative session and provide a novel and non-obvious method, system and computer program product for host state sensing for message interruptions. In one embodiment of the invention, a data processing system configured for host sensing for message interruption can include a messenger disposed is a host computing platform, prioritization logic including program code enabled to assign priorities to incoming messages, and host state sensing logic coupled to the host computing platform. The host state sensing logic can include program code enabled to adjust a threshold value for permitting message interruptions for messages having assigned priorities beyond the threshold value.

Abstract: The present invention provides a method and system for implementing asynchronous portal pages, comprising a portlet monitor resident on a web browser and implemented with a script. When a user interacts with a portlet, the portlet monitor sends a XMLHTTP request to the portal server. The portal server obtains the corresponding web contents from the corresponding portlet based on the request. Then, the web contents are modified and the HTTP requests therein are redirected to XMLHTTP requests. The portlet monitor uses the modified web contents to refresh the web contents of the corresponding portlet in the portal page without reloading the whole portal page. Besides, after the user submits a request for a portlet, during waiting for the portlet being refreshed, the user may continue to interact with other portlets. Thus, the present invention has the abilities of partially refreshing and asynchronous communication.
