title: Detect if my page is in a frame from code behind
body: <p>Is there a way to detect if my page is inside of a frame from my C# ASP.NET Code Behind?</p>
  
  <p>I know there are ways to break out of frames, or detect frames, using javascript, but I'm not interested in that for this case. I want to know if there is a way to detect the frame server-side before the page makes it's first trip to the browser, i.e. if there is some kind of indication of this in the request.</p>
