Well, the below issue is solved: I had to add the statement 'path = "/"'
or 'path = "/python"' when setting the cookie:
Cookie.add_cookie(req,
Cookie.MarshalCookie("basic", value, "gezellig",
expires = time.time() + 7776000,
path = "/"
))
And now it works all nicely. Apparently it started searching with the
original script as path ("/python/usertest.py") instead of
"/python/test.py" which was the path of the called script, and the path
set in the cookie.
Now only the importing issue!
