Hi, any comment about this please? IMHO this topic is important. If I'm wrong I would like to know it :) 2011/6/20 Iñaki Baz Castillo <ibc@aliax.net>: > Hi, I would like to start a new thread for this topic as it seems that > the draft does not cover it at all (just suggests that an HTTP > response code other than 101 should be threated as RFC 2616 states: > > > "1.
