I have developed a web app which runs on "Interanet" (not internet).
I am able to control multiple per user(I wanted to limit upto 5, i.e Same user can login 5 times). But what i need : 1)I want to restrict one login/signon per machine, i.e user should not be allowed login using diff browsers in a same system. I tried to capture IP address but since Intranet am not able to use "whatismyip" or any "json".
please help me. Thank you.
