This is certainly true for server-side multiplexing.

Client-side multiplexing is a much trickier proposition.  We use =
cookies,
setTimeout(), and window.open() to share JavaScript object references
between windows.  There is a slightly broken leader election protocol
to decide which window holds the persistent connection at any given =
time.
If all goes well, persistent connection migrates automatically when
windows are closed or new windows are opened.
