I have written code for authenticating with Salesforce. I am using Grant_type=Password. I am using some userName like "ABC" and password like "XYZ". I am making multiple request login with same credentials but i am getting same Access_Token again and again. So my question was-
1) Why i am getting same access token for multiple login request?
2) does Salesforce keeps user credential and Access_Token mapping at his end and check if login request comes again for the same user it returns the previous Access_Token?
