This is probably a corner case, but we should also consider Chromeframe which has a dual UA identity --see minutes of the 06/06 call http://www.w3.org/2012/06/06-dnt-minutes and http://www.chromium.org/developers/how-tos/chrome-frame-getting-started/understanding-chrome-frame-user-agent. I don't know if there are other example of UA switching. Vincent On 9/11/2012 9:01 PM, Roy T. Fielding wrote: > Yes.
