hello
My question is how to make a php page expire
i mean it should not reload from cache memory too
i have tried to use this but seems to be of no use
header("Cache-Control: no- cache: must -revalidate")
header("Pragma:no-cache");
but on reloading the page comes back
thi sshould not happen
users should not be allowed to access the previous pages by clicking back button of teh browser
can anyone help me?
regards
Roopa
