== 1-UA and 2-UA details ==
Hi everyone ;-)

In many places, we can find references to 1-UA and 2-UA ([Chromium 
Intent to 
Ship](https://groups.google.com/a/chromium.org/forum/#!topic/blink-dev/YKVnS429hns),
 Firefox bugzilla 
[#1184036](https://bugzilla.mozilla.org/show_bug.cgi?id=1184036) & 
[#1184073](https://bugzilla.mozilla.org/show_bug.cgi?id=1184073), spec
 Github issues...) but I cannot find a formal definition in the spec.

Here's what I understood :
* 1-UA is for non Web capable presentation displays, the UA initiating
 the request is rendering the page himself and mirrors it to another 
presentation display.
* 2-UA is for Web browser capable presentation displays such as the 
Chromecast, Matchstick...

The description in Bugzilla 
[#1184036](https://bugzilla.mozilla.org/show_bug.cgi?id=1184036) 
regarding 1-UA mentions the Chromecast. It confuses me. I thought it 
was a 2-UA presentation display.

In the Chromium Intent to Ship post, it says that 1-UA is not 
implemented yet but it will be before the end of the year. I'm 
confused when they say they will implement 1-UA even if browser 
vendors are free to do so. I can't find where the spec mentions that.

Thanks.
