or, a perfect usecase for a deque
if you put this at the top of your controller, every controller function
can access session.previous_url[0] as the last url visited.
from collections import deque
if session.previous_url is None:
session.previous_url = deque([request.url], maxlen=2)
else:
session.previous_url.append(request.url)
