@scytacki Yes. It is a crude cookie detection method used for sub-domains within the said domain (`.rites.concord.zeuslearning.com`). It uses the current user `id` from the cookie for auto sign in of the user. This was done as a proof-of-concept as using user's `id`s directly is not secure for use in a production environment (it becomes easy to spoof anybody's user id and get logged in as that user without authentication).
