Gary, Thanks for your reply. I'm beginning to think that that's what I'll have to do, although it will be a bit of work to convert. I'm surprised, though, that sessions aren't better in regards to data integrity. What I'm gathering from looking into this is that it's ok to use sessions, but you shouldn't count on reliable data from them. I don't remember seeing any caveats to that effect in the documentation on sessions, but that seems to be the case. Anyone know differently? Thanks.

I was initially using cookies, so I switched to propagating the

I noticed that the session data file name included the session id, so
I tried propagating the session id in the URL, and setting the session
id right before session_start() -- that resulted in two data files on
disk, but one session would occasionally write to the other session's
data file. At this point, this is the code I'm trying:
if (!array_key_exists('SESSION_ID', $_REQUEST)) {
$_REQUEST['SESSION_ID'] = 'SESS'.uniqid('');
}
session_name($_REQUEST['SESSION_ID']);
session_id($_REQUEST['SESSION_ID']);
session_start();
output_add_rewrite_var('SESSION_ID',$_REQUEST['SESSION_ID']);
In php.ini, I now have:
session.use_cookies = 0
session.use_only_cookies = 0
session.auto_start = 0
Also, I'm on Mac OS X Tiger, and everyone's using Safari. PHP 5.0.24a,
MySQL 4.1.22
Any suggestions on how to have unique session data for multiple
windows in the same browser on the same machine? Seems like it must be
doable, but I haven't figured it out yet. Thanks to whomever can help.

As far as I know, the only way for this to work reliably is if your
users can manually choose to open a new session in a new window/tab.
Is this the way you want it to work? Because you can't reliably stop
them from having the same session in multiple windows if they would so
choose.
On the other hand, why would you require multiple sessions if they are
to work against the same database? Will they be using different user
accounts to access it simultaneously, or some administration user with
authorization proxy to use regular accounts?
What kind of information stored in the session would require them to use
different sessions for different tabs? If you give us a hint, we might
be better able to help.

RE: [PHP-DB] independent session data for multiple browser windows
That just sounds like such recipe for disaster. What about running multiple
divs with each data set in that 'window'? Then you could pass each datasets
relevant ids along to keep thing separate...
Another option could to create multiple [i]frames and do the same thing?
