PublicShow sourcechat.pl -- The SWISH collaboration backbone

We have three levels of identity as enumerated below. Note that these form a hierarchy: a particular user may be logged on using multiple browsers which in turn may have multiple SWISH windows opened.

  1. Any open SWISH window has an associated websocket, represented by the identifier returned by hub_add/3.
  2. Any browser, possibly having multiple open SWISH windows, is identified by a session cookie.
  3. The user may be logged in, either based on the cookie or on HTTP authentication.
