You need to make sure that the page can be cached by the browser, which may be done by adding an "Expires: ..." header (or the equivalent meta tag).

Thanks for the reply, i used all the three tags pragma - set to no-cache, expires set to now and cache control to no cache,
in ie5 i found ok, but in ie4.01 service pack and netscape comm 4.7 i am getting error messages when i click on back.
one more thing, the pages which i submitted with post only iam getting the problem, please sugeest me to overcome this problem. and i don't want change the form method to GET.
