According to the standard, you should have in your HTTP headers an Expires line that should point to negative time to prevent any cache. Fortunately, if you are using CGI.pm, adding -expires=>'-1m' in the header() function will do this without problems. Be warned, of course, that these must be respected by the browser for it to work, and a homegrown browser or someone using something like LWP doesn't have to pay attention to said Expires; you may want to make sure you use session ids to track the user and prevent them from revisiting any part of your script that you are trying to prevent caching of.
