1.why don't you use $GET? instead of sessions? 2.you may also use cache-expire , so the browser will cache the last page wich was viewed. 3. you may also use a hidden form element to keep track of your current viewed page.(a little bit like using $GET)
and no, you can't detect from php if the user pressed BACK.
