I should apologize as I butted in without following the earlier mails. But your problem has got me interested as I didn't know the back button doesn't respect the cache settings.

I found this solution using "no-store" that appears to work for Firefox but not Safari. Can't test IE right now.

For PHP...
header("Cache-Control: no-cache, no-store,  must-revalidate");
header("Expires: Fri, 30 oct 1998 14:18:41 GMT");
echo date("Y:m:d-H:i:s");

For Livecode (not tested)

put header "Cache-Control: no-cache, no-store, must-revalidate"
put header "Expires: Fri, 30 oct 1998 14:18:41 GMT"
put the long time


Cheers
Dave
