Hello,

I have an mvc web application. Now i have a requirement to not allow the same/different user to login from same browser when a user is already logged in.

Please help to find a solution for this.

You can store active session
```
CREATE TABLE ActiveSessions (
    SessionId NVARCHAR(255) PRIMARY KEY,
    UserId INT,
    BrowserInfo NVARCHAR(255)
);
```
On User Login

Check Existing Sessions:

Query the ActiveSessions table to see if there’s an active session for the user with the same BrowserInfo.

Invalidate Old Session:

If an existing session is found, remove it.

Create New Session:

Insert a new record with the SessionId, UserId, and BrowserInfo
