RabbitMQ does *not* expect a 'server' header. The difference in the 
above is purely due to whether a 'host' header was specified or not.

The reason the first attempt fails is that the specified host is not a 
virtual host known to your rabbit. RabbitMQ ships with just one vhost, 
called '/', pre-configured. That's also what is chosen as the default 
when no 'host' header is specified in the CONNECT.

We should document this better. I have filed a bug.

While accepting a CONNECT w/o a 'host' header is technically a violation 
of the STOMP 1.1 spec, I don't think it does any harm and it means we 
can keep the CONNECT handling code version agnostic (STOMP 1.0's CONNECT 
does not have a 'host' header).
