title: Prevent back button
body: <p>I am using Razor on ASP.NET MVC with C#.</p>
  
  <p>I am calling an external web page to process a credit card and it returns to me. I then display a receipt. </p>
  
  <p>I'd like to prevent them from going back to the previous screen. </p>
  
  <p>I do not have an underlying cs page, like asp since these are .cshtml files, to grab the event.</p>
  
  <p>This receipt page is a View so I cannot put JavaScript in the header since it would affect every page using it.</p>
  
  <p>Anyone know how I prevent the back button in this circumstance?</p>
