Kamlesh, what you are talking about is tying a login to an IP address. You can invalidate the session ID if the IP address changes or ignore all new session requests while there is an active session under an old IP address. This can present usability problems to some users if their IP address changes. Another option would be to present an alert to the user that the IP address logged in has changed. For example, GMail lists the last account activity on the page. You should log these instances as well in case they present a security incident. You’ll likely want to put a decent portion of this logic in your login Action.

Hi Benjamin

Actually we are already using interceptor in our web portal, But in this web portal one user can login more than once simultaneously with the same username and password(username is unique).

It means if i logged in with username “kamlesh” and pw “123456″ even though other can login with username “kamlesh” ane pw “123456″ (the username is unique). I want to restrict this.

At a time Only one can login with one username. No one can login with username which is already logged in.
If you have faced this problem then pls help out me.

Regard
Kamlesh

Please do NOT use the “Open Session in View-Pattern”. This should only be an example to unerstand how interceptors works. The “Open Session in View Pattern” makes the View dependend on persistence layer aspects…
