Web Sockets is a transmission protocol, intended as a substitute for TCP/IP
where it is unavailable by policy.  (Of course, it is a TCP/IP overlay, so
TCP/IP must be technically available.)  TCP/IP is a transmission protocol
and it is useless without a communication protocol.  And so is Web Sockets.
I think the idea to use Web Sockets on the server is void; the server can
use TCP/IP at will.
Cheers,
Chris

Could it be that the URI/IRI entered is sent to a server, where there 
are no cross-domain restrictions?

My understanding is that there is a Web Sockets protocol.
