Detect if my page is in a frame from code behind

Question

Is there a way to detect if my page is inside of a frame from my C# ASP.NET Code Behind?

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.

Answer 1

Nope, there's nothing sent in the headers of the request indicating that the page is in a frame - and that's all you really have to go on.

The best you could do is take a look at the Referrer property, and if it comes from a known framing site (i.e. images.google.com etc) treat it as suspicious.
