From: FAQ server on 3 Mar 2010 19:00 ----------------------------------------------------------------------- FAQ Topic - How do I log-out a user when they leave my site? ----------------------------------------------------------------------- This cannot be done reliably. Here's why: * The user may disable javascript so the log-out script will never execute. * The user may not be on-line when they close your web page. * Javascript errors elsewhere in the page may prevent the script executing. * The browser may not support the onunload event, or may not fire it under certain circumstances, so the log-out function will not execute.
