Abstract: Mechanisms for allowing allow multi-session capability and session-return enabling stateful web applications include providing a start URL of a requested portal page with an “External Session ID” (ESID). The ESID is an argument that is different between the two instances of the application (on the same page), and leads to different/independent sessions in the server. When a user returns to the same page, the ESIDs are passed again with the individual application requests, and the server can then logically reconnect to the proper session and allow the user to continue. The ESID can be used to return to an application after the user has previously left to go to another application and then desires to come back, or even when the user closed the browser and restarts the application later.
