Greetings,

Just a quick clarification on something Dave was minuted as saying;

"DO: Consider multihop with HTTP first hop and JMS for second. Note
that wsa:address is for the ultimate destination, not the
intermediate. Mark believes that HTTP prohibits this."

The problem is with wsa:To, not wsa:Address per se, as the former is
the SOAP header which, when present in a SOAP/HTTP message, supercedes
the HTTP Request-URI as the provider of the "ultimate destination"
URI.

FWIW, this is partly the fault of the default SOAP 1.2 HTTP binding,
because it defines the HTTP Request-URI to be the address of the "next
hop", not the ultimate destination.  I think it's pretty clear (RFC
2616 sec 1.4, amoungst other places) that this is incorrect.

Thanks.

Mark.
