RE: [PHP] Re: sessions terminating randomly please help

Assuming that php is configued to rewrite the url tags, try turning off cokkies in the browser and let the Session if carry over. This might help you debugg it. -----Original Message----- From: David Chamberlin [mailto:dwc@nautiboy.com] Sent: Monday, March 10, 2003 3:41 PM To: php-general@lists.php.net; Freaky Deaky Cc: php-general@lists.php.net Subject: [PHP] Re: sessions terminating randomly please help Importance: Low It's possible you're being afflicted with the same problem I am. See the message just one or two above this about "Sessions problem". What I found in my debugging is that it had to do with how I was mix-and-matching the way I specified links. Short version of the problem is that http://mysite.org/ has one session and http://www.mysite.org/ has another. In my code, I sometimes have the links as <a href="/<page>"> and sometimes it's explicit, as <a href="http://www.mysite.org/">. So if a user went to the site as http://mysite.org - the pages that used the explicit www.mysite.org would fail. So if there's anything in your pages/links that may change how the link is referred, you may be have different sessions occuring. I would imagine it should be pretty easy for you to debug whether or not this is the problem. Have each of your pages echo out the current session id (echo 'session is '.session_id().'<br>';) and see if it changes at any point, and especially on the pages that fail. -Dave Freaky Deaky wrote: > hi > > i am experiencing a major problem with sessions expiring randomly in some of my > apps. i will log in and start clicking around and then i will eventually > arrive at a page that tells me that i'm not logged in anymore. this happens > apparently randomly. i have seen it on ie6, ie for mac, netscape 4.7 for pc, > and mozilla > > the apps are hosted on > > freebsd 4.7-release p2 > apache 1.3.27 > php version 4.2.3 > compiled with --enable-trans-sid > > i can't go into production if there's the possibility that users will be > randomly logged off. i went through all of my code over the weekend, and i > don't think i can attribute this to a miscoding: > > when a user logs in, i create a session with > > session_start(); > $valid_user=$_POST['username']; > session_register("valid_user"); > > i have the following code at the top of each page to check to see if the session > is valid: > > session_start(); > $valid_user=$_SESSION['valid_user']; > global $valid_user; > if (session_is_registered("valid_user") > {...function to spit out an error message if the session is not valid...;} > > i have a logout page that destroys the session > > session_start(); > session_destroy(); > > i also have a javascript timer in the header of every page that redirects to the > logout page if the user has been inactive for 20 minutes. > > i have played around with session.gc_probability, setting it to 100, but that > doesn't seem to have fixed the problem. > > this is a huge problem. > if anyone can give some advice, i'd really appreciate it. > > thanks > -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
