The cache-control directives are only supposed to be followed if the page was to be _explicitly_ reloaded or refreshed. The BACK button (as specified in the standards rfc XXXX something or another) is NOT supposed to reload or refresh a page -- it is supposed to redisplay the page from the cache. Buggy browsers like NN, IE & Mozilla etc reloads the page. Well behaved browsers like Opera redisplays from cache and hence your problem.

Ah ... so using cache control is *not* the way to solve my problem ... As Justin pointed it out I should be looking into solving this within my site "logic" then I guess ... Does anyone know of any good online references or even books where I could read up on on to build "logic" into my site. All the PHP books and references I have are great from a programming point of view but they hardly mention anything about site navigation/logic and how to implement it in PHP ... Thanks! Jc
