"4. The BOSH Technique" says:
"If the client has data to send while a request is still open, it
establishes a second socket connection to the connection manager to
send a new request. The connection manager immediately responds to the
previously held request (possibly with no data) and holds open this new
request. This results in the connections switching roles; the "old"
connection is responded to and left awaiting new requests, while the
"new" connection is now used for the long polling loop."
So if you know that there are other messages pending at the client, do
not use hold/wait until your sending queue is empty. If during a hold,
the client needs to send a new message, open/reuse the secondary
connection, if it needs to be sent before the wait interval has
expired.
