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.
