How to authenticate from Frappe using Cross Site Frontend App with Session?

Hi everyone.
I was wondering about the authentication using Frappe API /api/method/login.
But the situation is when I make the request to the server, it returns OK 200. But the session is not sent back to the client side, so I can manage the session. Please try to help me out, how can I manage the session and proceed other API workloads using the same session and after that I can proceed to check whether the user is logged in or not and logout.
