Bryan, The tricky detail in your scenario is the non-persistent cookie. (See note at bottom for details on persistant/non persist cookies)
Now, when you launch a New browser via CTRL+N, it gets a copy of ALL the vars in memory at that time from the original (including your non persistant cookie). However, when you launch a new browser via the link, it will open up a new instance in it's own memory space and thus does not have the cookie existing. The reason for the 'Taskbar' 2nd browser not running in the same memory space as the first two is probably due to the little tick box on the shortcut which says 'Run in seperate memory space'. (Win2k, if it's not Win2k .. then ask Microsoft :-) If we wanted a web application to be able to have mulitple logins from the same workstation, I would use a seperate cookie name. <side note> As you know, when the cookie is persistent, it is stored on disk, for all and any instances of that browser to see. So if you closed a browser (and the cookie didn't expire, and the session didn't expire) and opened a new browser within the session/cookie timeframe, then you will of course get the existing session. </side note> hope that helps, I may be off is some places (all ?) but from what i can tell and my experience this fits the bill. cheers Ramon Buckland > -----Original Message----- > From: Bryan Stevenson [mailto:[EMAIL PROTECTED] > Sent: Thursday, 3 April 2003 8:53 AM > To: CF-Talk > Subject: Cookies and browser launch methods > > > Hey All, > > I've just bumped into a situation I haven't seen before and > am wondering if > anyone can explain why this happens. > > The Situation: > A site that uses a sessions table in the DB and stores the > session ID in a > non-persistent cookie once the user logs in.
