Session Expire / Object Destroy

Hi All

I am wondering what is the best way to do this. Let's say I have JSP Dynpage with a HTMLB Form containing an search text field. Users does the search and results are displayed in a htmlb table on it using the hbj tags. I have stored the model for this table in the IComponentProfile. Lets say user Amy visits this component via the portal. See enters some search text and sees some results in the htmlb table. Then the user closes the browser and visits the same component after an hour. Fun part is users sees the same table again.

Is there way to get rid of this behaviour.

Thanks and Regards
