Can you clarify the reason to prefer srv over something like an Alternate-Protocol response header? I can see that Alternate-Protocol is suboptimal in that it requires waiting for a response first, but I have concerns about adding yet another DNS lookup. Chromium has already lowered our concurrent getaddrinfo() calls to 6 due to problems with home routers not being able to handle too many concurrent DNS queries. Adding more DNS lookups per hostname will further exacerbate the problem. In any case, FWIW, I hope websites simply transition to https:// URIs instead :) On Wed, Aug 15, 2012 at 6:00 AM, Patrick McManus <pmcmanus@mozilla.com>wrote: > On Tue, 2012-08-14 at 12:24 -0400, Phillip Hallam-Baker wrote: > > > If we take architecture seriously, the primary signaling mechanism for > > HTTP/2.0 should be some form of statement in a DNS record to tell the > > client 'I do HTTP 2.0'.
