Cookies from a previous request made in the currently running
program?  Or cookies from requests that were made when you previously
ran the program?

Examine this code and its output:

class SmartRequest(object):
    def __init__(self, id):
        if not getattr(SmartRequest, 'cj', None):
            SmartRequest.cj = "I'm a cookie jar. Created by request:
%s" % id


r1 = SmartRequest(1)
r2 = SmartRequest(2)

print r1.cj
print r2.cj

--output:--
I'm a cookie jar. Created by request: 1
I'm a cookie jar. Created by request: 1
