Circumvent cache with random number parameter

« Posted 2010-01-06 12:33:54 »

So i've found somewhere a clue to bypassing the caching of an applet: add a random number parameter, somewhere.
but i'm not very clear yet exactly how to do this: generate a random number with javascript and then what? - where do i put it, how do i pass it?
I'm trying to cobble something together but am really bad in html, would appreciate a clue as to what i'm doing:

You would pass it in the archive attribute, since that is the resource being downloaded from the server.

This should work:
