DotNet Postbacks Not Working in IE11

Physical Link: DotNet Postbacks Not Working in IE11

Many people are posting the woes of DotNet Postbacks not working in IE11.  I too experienced this and remembered that there were app_browser files that could be modified to give the browser further instructions.  With a quick google search I was able to find the exact solution that I was looking for.  I cannot take credit for it so I will share the original URL from which I got my answer.

However Here is the code so you do not have to click on the link above:

   <browser id="IE11" parentID="Mozilla">  
       <userAgent match="Trident\/7.0; rv:(?'version'(?'major'\d+)(\.(?'minor'\d+)?)(?'letters'\w*))(?'extra'[^)]*)" />  
       <userAgent nonMatch="IEMobile" />
