Session cache problem ?

Hi everyone. I have a problem with the session cache. When I set it to nocache, when I click on back on my browser, the page is reloaded and of course I loose the forms content. I believe this is the normal behaviour of this setting. Now if I put the cache on public ou private, this page is not reloaded, BUT, and this is were it gets weird, if I click on reload on IE5, the page won't update its content. I see on the logs that IE loads the page, but it displays the old one ! Something is terribly wrong here. I have the same problem with RC1 or latest CVS. Is there any way to simply disable the cache header so I works like in PHP3 ? J-F Mammet webmaster@softgallery.fr
