I can assume that you use the session, or whatever, to track someones 'logged in' status?
And that you only check the credentials against the values in the DB when someone
actually submits a login form?
Then there is no reason as such to create the DB connection on every request,
although you should consider that you may be connecting to the DB for other
data than just login credentials regardless of 'logged in' status.
Are you using a *_connect() function or a *_pconnect() function?
*_pconnect() creates a persistent connection (assuming your setup allows
it) - though there is no garantee that a request will use the same connection,
because there is no garantee that a specific webserver process/thread will
handle a given http request - each webserver process/thread (normally?) has
its own persistent connection to the DB.

show us auth.php, if you can/may.
also try:
var_dump($dbh);
....in code to see what it contains on each request.
