title: Is it still valid to use IE=edge,chrome=1?
body: <p>I read Chrome Frame closed last month, I thus tried to understand what it'd mean for the X-UA tag and after 3 hours of research I still didn't find the answer I'm looking for, my question is the following :</p>
  
  <p>Is it still valid nowdays to use IE=edge,chrome=1 or should I stop at IE-edge from now on ? Or what would be the best pratice to do regarding X-UA, should it be avoided ? </p>
