Method and system for providing asynchronous portal pages

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.
