My webhost has this to say in a kb article re this problem:
PHP Sessions do not work as expected
Symptoms:
* Sessions are not saving when transitioning from HTTP to HTTPS
protocols. If a PHP session needs to begin in HTTP and switch to
HTTPS, there will be some issues where the session is not maintained
across that transition.
* General problems with sessions not seeming to be carried across
web requests.
* Sessions in general behave inconsistently. Your script has a
dependancy on writing data to the /tmp directory.
NOTE: [Although this workaround is intended for a few issues we've
noticed in regards to specific cases, this will most likely fix a
large majority of cases where you're having problems with sessions
working properly - if you are having problems with sessions and your
symptoms don't quite exactly fall into the description above, we
suggest you try this workaround anyway.]
Solution:
This can be fixed by configuring a directive inside of a custom
php.ini file to explicitly direct session files to save in a local
directory on your (gs) Grid-Server instead of the default global '/
tmp' folder.
NOTE: If you are not yet using a custom php.ini file on your server,
you may follow this KB article on the process before proceeding with
the steps in this article.
NOTE: It has been reported that PHPMyAdmin does not work once you make
this change. Here is how to use a desktop database tool as a
workaround to this side effect.
The directive that must be placed inside of your php.ini file is:
session.save_path = /home/####/data/tmp
Where '####' is your actual site number.
so, for s1234.gridserver.com, you would use the following:
session.save_path = /home/1234/data/tmp
After saving these changes, make sure to navigate to your 'data'
directory and create a folder called 'tmp'. The next session created
will start behaving properly and the problem should no longer occur.
+++
Great! I will have to give up PHPMyAdmin for them to fix the problem!
No way! I rather look for another web host!
By the way, I have tested this a bit further. After visiting from
three to twelve pages I lose the session variable for loggedin. I have
swtiched between the same pages and it happens sooner or later.
