Well, after 10 years with CF, I learn something I should have learned with CF 4.5.
I thought cookies were on the hard drive and session variables were in memory only. I figured that's why there were separate settings for client management and session management all this time. Concerning "another app" setting cookies... I had "this.setClientCookies = false" specifically set in this app. Would another app on my local machine still be able to set cookies that would affect this app? There's not another app with the same application name... > -----Original Message----- > From: Dave Watts [mailto:[email protected]] > Sent: Wednesday, January 07, 2009 8:14 PM > To: cf-talk > Subject: Re: Desparate!!!!
