This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The read-only property RTCIdentityErrorEvent.protocol is a DOMString describing the Idp protocol in use.

Firefox implements the interface of this property under the following name: RTCPeerConnectionIdentityErrorEvent. It is likely that it will correct this name when it will unprefix RTCPeerConnection, once spec and implementation will have been stabilized.


var protocol = event.protocol;
event.protocol = "idp.html";


pc.onidpassertionerror = function( ev ) {
                           alert("The idp uses the following protocol '" + 
                                 ev.protocol +
