User "A" logged in to your web site and he is using Mozilla firefox browser after his logged in , i have stored some value in Session , now user again logged in from Internet explorer. So what will happen , can i get the session value for this user ??
this user is allowed to logged in ???
Also You have to specifically avoid such scenarios in future because It could lead to problems like Session Merging which would really cause multiple problems for you and could hamper your application functionality..
