Understanding the Ulterius ID

The Ulterius ID is a websocket cookie set on the client's browser upon first connection to the Ulterius server.

If you are writing a non-web browser implementation of the Ulterius client, be sure your websocket library supports cookies. It does not have to be persistent, however, there are some inherent security benefits to using a persistent cookie.

Only a single valid session can exist for an Ulterius ID. An attempt to log into Ulterius in one tab and then in another will result in the Ulterius server rejecting the connection and sending an alert to the original session.

Ulterius IDs are persistent to a single browser, but not across browsers. Private browsing modes (e.g. Incognito, InPrivate, etc.) will result in a new ID.
