I read that with each kite connect App there can be 3 separate web socket connections. But i see that there is only one redirect URL option. So when 1st websocket is running and i try to login the 2nd one it gives port already is use error which is obvious. So how can 3 separate websockets be established using the same redirect URL?
A redirect URL is called in the login process after successful login. A user can use the request token to get an access token. Once you have an access token, you need to reuse it and not create a new one since it will be live till the next day morning.
