Hi Laxminarayan
The standard way of doing this is to authenticate your user against a
database and deny access if they are logged in already.
For example. when a user logs in, set a field in your database called for
instanced "online" to 1. When they logout reset it to 0. When a user
logs in, you check the value of this field against their username in the
database and either deny or allow access.
