title: Detect if any kind of IE (MSIE)
body: <p>I dont want to allow users to access my site with Microsoft Internetexplorer (ANY VERSION).</p>
  
  <p>What I´ve found so far was to detect if it´s lower or equal version 10.</p>
  
  <p>A very annoing thing: Internetexplorer >v10 doesn´t admit to be a InternetExplorer.</p>
  
  <p>What i´ve found and tried so far:</p>
  
  <pre><code>if(navigator.appVersion.indexOf("MSIE")!=-1){
  alert("You use IE. That´s no good.");
  }
  </code></pre>
  
  <p>or</p>
  
  <pre><code>if ( $.browser.msie ) {
  alert( $.browser.version );
  }
  </code></pre>
  
  <p>and</p>

  <p>I would use any solution if it is in javascript, jquery or php if there is one.</p>
