Subject: Re: SOAP-over-UDP
Thank you all for your very quick reply!
I've heard about this SOAP-over-UDP spec
(http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnglobspec/html/soap-over-udp.asp).
So, Martin, you say that it could not be a solution? Perhaps it should
be an idea using Mark's solution (with DNS).
I thought to resolve the problem putting a SOAP envelope into a UDP
datagram, send the datagram to a broadcast ip and that's all
folks...but I don't know how and, as you, Martins, wrote, I was not
able to find anybody who has implemented this yet.
Can you suggest me another solutions?
Thank you very much again!!
Cheers,
Francesco

I would caution on use of UDP as the SOAP Portocols (e.g. HTTP) is/are
decidely not UDP but instead a connection-oriented TCP
To date I have not seen UDP Ports used for SOAP transmission although
since
there is no requirement for verifiable connection and or handshakes
I would venture to guess UDP is available as the transmission medium but I
have not seen any UDP Ports used for SOAP thus far
Anyone else ???
