Good day, By default, IE will cache these pages (i.e. you won't get this message).
If you're receiving that message, it means that the browser doesn't have a cached version of the page. Getting a new version would obviously mean submitting the form information again, which IE, thankfully, doesn't automatically do. It may be that the IE users aren't caching their pages, or the cache is automatically cleaned (had this happen once with users writing onto their profile). Or, it may be that meta tags on the page have instructed the browser not to cache the page, or to quickly expire it. You should check the page source for such headers. I know it is tempting to trash-talk IE, but in this situation, regardless of the problem, most likely the browser is just doing what the user or web page has instructed it to do. ============================ Darren Gamble Planner, Regional Services Shaw Cablesystems GP 630 - 3rd Avenue SW Calgary, Alberta, Canada T2P 4L4 (403) 781-4948 -----Original Message----- From: Lee P Reilly [mailto:[EMAIL PROTECTED]] Sent: Monday, January 28, 2002 3:27 PM To: PHP List Subject: [PHP] browser back button - "Page has Expired.. " problem Hi, I wonder if anyone can offer me a few pointers..? I'm building a portal to do various bits and bobs. I'm using sessions to facilitate the user authentication/login, etc. The only problem I have is that when viewing these (.php) pages in IE once the session variable has been set, a "Warning: Page has Expired " page is displayed whenever the 'Back' button is pressed. This means that the user can only access the page again by hitting 'Refresh' (and therefore posting the form data back & executing whatever scripts again). The rest of IE's error message reads, "The page you requested was created using information you submitted in a form. This page is no longer available. As a security precaution, Internet Explorer does not automatically resubmit your information for you." I know from using other web applications (Hotmail is one example), that this doesn't always have to be the case. Is there anyway I can eliminate this security precaution on the *server side* i.e. without telling users to ditch IE ;-) Thanks very much in advance for any advice. - Best regards, Lee -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED] -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
