ASP.NET, closing browser window
<p>Suppose I have an ASP.NET registration wizard. The collected information for each step is temporary stored in a database table, when clicking “Next”. Now suppose the user closed the browser window, or computer was unexpectedly shut down. So in that the application should delete all the temporary registration information. How could it be done?</p>

<p>Additional information:
I cannot use cannot use a Session object because the application is served from a webfarm.</p>

<p>I thought already about using a stored procedure for clean up the table. But want to find out other possibilities. </p>
