[PHP] Re: sessions terminating randomly please help
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.

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

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.

Re: [PHP] Re: sessions terminating randomly please help
Check if your server is using files or shared memory to save the sessions...
My ISP was using mm (memory), and it was buggy... when they changed back to
files, all was well.
