title: Clear cache with greasemonkey
body: <p>I have a web application running in a kiosk, which is set up with greasemonkey so that we can customize little things about the application and ensure the customizations only occur at the kiosk.  I have been digging through the GM api hoping that it would have some functionality to affect browser settings, but alas it looks like it only affects pages running in the browser.  Is there a way for me to tell the browser to clear it's cache when a certain event happens in the application?</p>
