How to detect IE11 from User Agent?

Pre-IE11 versions of Internet Explorer browser have a common pattern/string i.e. "MSIE" within their user agent string. But that is not the case with IE11.

IE11 user agent string

Mozilla/5.0 (Windows NT 6.3; Trident/7.0; rv:11.0) like Gecko

IE10 user agent string

Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.1; WOW64; Trident/6.0)

Here is some JavaScript code to identify the version Internet Explorer from user agent string

var isIE11 =  navigator.userAgent.match(/Trident.*rv\:11\./);

var isIEButNotIE11 =  navigator.userAgent.match(/MSIE (\d+\.\d+)/);

This function can be used to get the version number of IE

function IEVersion() {

    var ieversion;

    if (/MSIE (\d+\.\d+);/.test(navigator.userAgent))
        ieversion = new Number(RegExp.$1);
    else if (navigator.userAgent.match(/Trident.*rv\:11\./))
        ieversion = 11;

    return ieversion;
}

What is My User Agent?

I found this website today while I was looking for differences between User Agent value of IE11 and other older versions of IE.

When you open the website it will display your user agent string and IP address as well.

X-Frame-Options response header

The X-Frame-Options HTTP response header can be used to indicate whether or not a browser should be allowed to render a page in a <frame>, <iframe> or <object> . Sites can use this to avoid clickjacking attacks, by ensuring that their content is not embedded into other sites.

Using X-Frame-Options

There are three possible values for X-Frame-Options:

• DENY

  The page cannot be displayed in a frame, regardless of the site attempting to do so.

• SAMEORIGIN

  The page can only be displayed in a frame on the same origin as the page itself.

• ALLOW-FROM uri

  The page can only be displayed in a frame on the specified origin.
