Detect iframe error APPHOST9613

Question

Hi, 

Is there a way to detect iframe error APPHOST9613 FORBIDFRAMING?

"APPHOST9613: The app couldn’t navigate to http://www.facebook.com/worldmarket/posts/10151120077917735 because of this error: FORBIDFRAMING."

I can see the error in javascript console.  We would like to capture it programmatically and send the user to a browser when the error occurred.  But 

Ideally, we want something like the WebView in C#, so that we can simply display any web page.  Currently, iframe does not show web pages that has x-frame-options, but WebView can.  I am really hoping a fix will come soon.

In the meantime, I am thinking about detecting this error and send them to an external browser if the page cannot be displayed in iframe.

Hi,

These sites have set the X-Frame-Options header.  More details, please refer to:http://blogs.msdn.com/b/ieinternals/archive/2010/03/30/combating-clickjacking-with-x-frame-options.aspx

Thanks for the reply, I know that already.  I am looking for alternative way to deal with it such as detecting error APPHOST9613 and open an external browser.  

Also, C# apps has the capability to embed those sites with WebView and HTML5/Javascript app do not have the capability is really troublesome.  Could you please reflect this to Microsoft that this is this major capability difference between C# and HTML5/Javascript.

Answer 5

Hi,

I have confirmed that you can't intend to make that as webview in C# app. And there is no way to trap the error however it is a header so if you can test for that header you will be able to detect this:
