Affan Dar commented on PROTON-160:
----------------------------------

I think the assumption behind option (1) was that adding a connection level 
setting (such as an alias) may not be appropriate for the level that the 
messenger API is operating it. Seems like that is not a big issue which is 
great. Connection aliasing is a good solution and will work for all scenarios 
(reconnect, redirect etc). It will also make the receive side more symmetric 
with the send side which is goodness.

> In a scaled-out, multi-tenant broker environment, the host on which the 
> container is running is often different from the host to which a client is 
> establishing the tcp connection. The 'hostname' field in the connection open 
> performative was added to support this scenario. Currently there's no way to 
> control this from the Messenger API.
> Options include:
> (1) (preferred) add a new 'networkhost' field to Message to allow the network 
> address to be specified. If provided, this information would be used when 
> establishing the network connection and the data in the 'address' field would 
> be used in the connection open hostname field. This is somewhat in line with 
> the way that connection redirect (amqp:connection:redirect) is specified.
> (2) extend the syntax of address with query string to supply hostname, e.g., 
> username:password@tcpaddress:tcpport/entityname?hostname=foo where 'foo' 
> would become the hostname used in the connection open frame. This is the 
> approach used by the current Qpid AMQP 1.0 JMS client.
