MySQL Connection

[Luis Briones]

I'm trying to write a perl script that would perform a specific function as soon as a user disconnects from the database. For example, I want the value "connected" to be inserted into a column as soon as the user opens the web page that has the perl script running. So this I would do as soon as the page loads. But if the user closes the browser or the computer crashes or something like that, I want to insert the value "disconnected" into that same column

Thanks
