Hi guys - I&#039;ve a question regards using application variables. <BR><BR>I want to ensure that only one person can log into my site at a time using a single set of details (no lending of logins). I was thinking of using an application object to flag whether a user was currently already logged in so any further login attempts with the same details will be denied. I could think of two ways of doing this, either with one application variable per person logged in or with a single application variable with all the login names in a comma delimited string. I was wondering if there were any preference when the number of users may be verging on a thousand.<BR><BR>Cheers for any comments.<BR>Pete.
