I use cookies to store stuff from that page, because I can write into  
them on the fly using JavaScript (onClick etc) - when they change  
pages, the cookie is written into Session variable, waiting for the  
final pages...

<meta http-equiv="Pragma" content="no-cache" />
<meta http-equiv="Expires" content="-1" />

For html cache-busting. Tested on:

Win XP - FireFox, IE6, IE7, Opera 5
Mac OS X - Safari, FireFox

Given that every browser implements this differently, you can probably  
add in other meta-http headers that indicate it expired in 1970, or  
was created in the future, but just those two seem to give me  
acceptable results on the common browers
