 Description  « Hide
as commented in chat... we need something related to sessions in new stuff.

Analyse the possibility to use $DB (will save one connection compared with current approach).

And also the possibility of specify different $DB.

just to avoid forgetting about it.

adodb sessions are not working at all in 1.9.x and before, because it lacks session locking code (== multiple open windows or linked files override each others changes)
we need something better in 2.0 ;-)

+1 for this, here at SFSU we running a really big site on a VM system (VMWare), and we are seeing some session-related issues that lead to slow performance....
