Re: [PHP-DB] Warning: Page has Expired
POST is no more secure, realistically, than the GET method. Both pass data around in plain-text form. In a perfect world web browsers wouldn't cache pages which were POSTed to as the HTTP specification says. At least, that's my understanding of it. Browsers -are- free to cache GET'ed pages though, because logically if the URL is identical to the other one the same data will be returned. So, switching to GET makes sense, because so long as the URL is slightly different each time the browser won't cache the page. Of course, in the real world not all browsers were made to spec, and some cache POSTed pages. So, to the original poster: It seems like your page is doing the Right Thing... but your browser isn't.

Re: [PHP-DB] Warning: Page has Expired
Actually, if you set it to be completely blank, it seems to let the browser handle the cache. I did that and have never received a page like that since then. I researched this for about 2-3 days straight, trying everything I could find. This seems to be the best method. Every once in a while you will get a cached page if you use your back button - but its extremely seldom. - Jonathan "Dave Watkinson" <[EMAIL PROTECTED]> wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... look in php.ini (or whatever the Linux equivalent is) for session.cache_limiter and set it to session.cache_limiter = nocache HTH 8^D Dave -Original Message- From: olinux o [mailto:[EMAIL PROTECTED]] Sent: 03 September 2001 19:34 To: [EMAIL PROTECTED] Subject: Re: [PHP-DB] Warning: Page has Expired I have the same troubles.

RE: [PHP-DB] Warning: Page has Expired
I consistently use the POST method when submitting a form to a PHP script. I seldom use GET. -Original Message- From: olinux o [mailto:[EMAIL PROTECTED]] Sent: Monday, September 03, 2001 1:34 PM To: [EMAIL PROTECTED] Subject: Re: [PHP-DB] Warning: Page has Expired I have the same troubles.

RE: [PHP-DB] Warning: Page has Expired
Keith, I believe this happens because most browsers feel that it is important to regenerate any page that was generated with form input when you go 'Back' to it. Therefore, there's not much you can do about it... I suppose you could make links from the expiring page open in new windows, so they could just close the window and it will be okay... but that's not a very good solution either, is it => Good luck, Ben -Original Message- From: Keith Spiller [mailto:[EMAIL PROTECTED]] Sent: Wednesday, July 11, 2001 6:43 AM To: Php-db Subject: [PHP-DB] Warning: Page has Expired I've setup a members directory in mysql that is searchable via different field and I limit the number of records. I use session variables to remember the number of records to display, what the starting record is, what the search string and search fields are. At anytime a user can click on an id number to do a Select statement that queries for that single row of data. Afterward, if the user hits their browsers back button I get: "Warning: Page has Expired" I've noticed allot of sites just ask the user to not use the back button. I'm curious if this is caused by an error in my code or because I used session variables that might have changed in the last MySQL select query. So that when you hit back, the browser is using some sort of cached data while still loading the php code? I'm very confused at this point. Is there anything I can do to prevent the "Expired Page" warning, rather than expecting my viewers to learn to do without it.
