How to block parallel login?
How can I block multiple login attempts in to a single account, when that user have already logged in?
Like... Yahoo/Hotmail email accounts...
1. When I logged in, using <username: russell> & <password: 123> from <my pc: xunit>
2. Until I logout or close my browser, the system should not allow me to login again from <my pc: xunit> or from any other pc, using same <username> and <password>.
How can I solve my problem? Please help…
