The present invention relates to the field of network computing, and in particular to method and system for designing a Web Portal including a hierarchical structure of portal pages and portlets for accessing Web contents accessible via the Portal. In order to increase the user comfort, a context exchange mechanism is includes defining a storage area for a single thread of processing by multiple applets on the Web portal, listening to events fired by each of the applets used by a user during processing by the multiple applets, collecting and storing the information associated with the listened to events in the storage area, wherein a piece of information is stored as a pair of an attribute and an attribute value, clustering the stored information into multiple different attributes, and propagating the clustered information automatically into the multiple applets.
