Once you've stopped them clicking f5 you'll need to stop them selecting refresh from the context menu, or clicking the refresh icon in the address bar. Then a new browser comes out where f6 is refresh and not f5, what do you do then?

You're thinking about this from the wrong angle, rather than trying to stop the user doing basic browser functions (which you can't) you should fix your code so it doesn't error when the user refreshes.

Short answer: you don't. You don't have control of client side of browser.
