Unique identifier for user in browser without login

Question

I operate a small shop online and I would like to allow users to buy stuff even if they do not have an account. For that, I need to connect a basket of selected items with a user. I thought using the ip address, but I noticed that it is actually not that easy to get the ip address. I am sure people have encountered that problem before? What is the best solution? thanks carl

Answer 1

thanks for the replies. Following the hints given above I solved the problem by generating a session id. In flask that's done using

import uuid
session['uid'] = uuid.uuid4()

Flask also seems to have a 'sid' element in the session object (session.sid), which apparently does the above automatically... but that did not work for me?
