Processing cookies at response time included cookies
that were temporary, like the JWT cookie that is
created by the server by combining the JWT header-payload
and JWT signature cookies. Since we are trying to monitor
the cookie header, we do not want to process this cookie.
However, since we want to include the user id in the logging
message, we delay the logging until response time.
Also, fixed docstring which mislabeled a custom attribute.
