title: Misunderstand of <meta http-equiv=”X-UA-Compatible“ content=”IE=edge“>
body: <p>I can not realize the real point of the meta http-equiv="X-UA-Compatible" content="IE=edge.</p>
  
  <p>1) If some users have some version of IE and he try to open concrete page, the page will be open in the version of IE Which user have (the latest version). I do not understand why we need that tag to maintain that?</p>
  
  <p>2) If user explicitly say that his IE (IE9 for instance) want to open the browser page as some previous IE version (for instance IE8) will this meta tag prevent it?</p>
  
  <p>3) What if I have IE7 or IE8 and this page has a meta tag? That page will be open in IE7 or IE8 Depends which version of browser I have already have as the latest on my computer.</p>
  
  <p>I really can not see purpose of this meta tag (except situation that user already adjust new version of the browser to open a page as older version), or I missed something here.</p>
