title: How to Configure IIS Express for mp4 videos
body: <p>I have written an application using C# ASP.Net MVC which in its Home View lists all folders of a Directory in a table. Each <code>tr</code> has a single <code>td</code> and <code>td</code> contains <code>a</code>. Clicking on <code>a</code> (folder name) replaces a <code>div</code> of Home View with a partial view which in turn lists all mp4 videos along with duration of that folder in similar way and I have used <code>jQuery AJAX</code> for such replacement. By clicking on VideoName video gets played and I have used <code>video</code> tag and specified  <code>type="video/mp4"</code>. </p>
  
  <p>I have added a Website in IIS Server where hostname is tutorials.com, physical path is App path and in binding  I have used 192.168.1.3 : 80. In DNS Server I have created a Primary Zone named tutorials.com and in a record used the same IP. I can watch video tutorials from any PC of my local network without any issue. </p>
  
  <p>If I open the application in Visual Studio and press <code>F5</code> or <code>Ctrl+F5</code> it starts using IIS Express and when I click on Videoname some videos are rendered properly and some do not. How to configure IIS Express to solve the problem?</p>
