when you ask for a cookie for a given key, if it doesn't exist it will be
empty.
as in code above. I don't think you want to worry about the cookie
existing with an empty value.
That wouldn't be a valid login.
Then if the cookie exists, you could do a db query to make sure the id is
actually in the database.
