# Please Don't Do This.

Browser detection is known to be very unreliable and is not future proof at all.  
<sub>As evidenced by you having this problem in the first place.</sub>

Instead, detect browser features and deliver what you need to based off those.

Ex:



    if (!!navigator.userAgent.match(/Trident.*rv\:11\./)) {self.location = "google.com"}

I must redirect IE user to other website and from IE6 to IE9 this code working very good:

     

This code working very good for IE 10:

     <script type="text/javascript">if (navigator.appName == 'Microsoft Internet Explorer'){self.location = "google.com"}</script>

But I can't find any solution for IE11 - in this browser my website doesn't redirect.

Maybe you know how to write only one script to redirect all IE browsers to other website?
