There is no event specifically for the back button. The "onunload" event will fire, but it will also fire for any navigation change.

You could try using a cookie.

You could check history.next to see if it is not null, but this requires an additional security privilege, and therefore a signed script. There is information on signed scripts here (http://developer.netscape.com/docs/manuals/communicator/jsguide4/sec.htm#1015075).

You might also be able to use history.forward() to prevent the user going back (i.e. when they go back they move forward again immediately) but this might not be suitable.
