Sample code for blocking IE in an OpenTok Application

gistfile1.js

// Detect whether this browser is IE
var isNotIE = function isIE () {
  var userAgent = window.navigator.userAgent.toLowerCase(),
      appName = window.navigator.appName;

  return !( appName === 'Microsoft Internet Explorer' ||                     		// IE <= 10
           (appName === 'Netscape' && userAgent.indexOf('trident') > -1) );     // IE >= 11
};

// If the browser is not IE, and it meets the minimum system requirements for the OpenTok platform,
// then create your app
if (isNotIE() && OT.checkSystemRequirements()) {
  var session = OT.initSession('your apiKey', 'your sessionId');
  // ... continue with your OpenTok application
}
