title: Deleting cookie of the instagram authorization page in rails application
body: <p>In my rails application i am using oauth to get access to the user's profile data. The thing is when the instagram's authorization log-in page pops up, the user has to enter his log-in details, a cookie gets saved in my machine. Is there any way to DELETE this cookie(obviously not manually)? I am asking this because when the oauth page is called again, this cookie saved in my browser automatically signs in the user.  This has become a nuisance for my project. I don't want this to happen, i want the same log-in page to be displayed again. </p>
