Asp.Net MVC site not showing in iFrame

I had an ASP.Net webpages site working fine (it's a booking application that people link to - a hosted service).

Some people just allowed a link to my site/application to open in a new window. Other embeded it within an IFrame on their site.

I have started updating it to MVC - however, the MVC version no longer works within an IFrame.

Is there any way, within IIS7.5 or within the controllers in MVC, to allow my application/site to display wihin an iFrame?

Thank you,

Mark

Do you have an example of what it is or isn't doing? Are you getting an error? Off the top of my head I can't think of any reason that the server-side technology (WebForms vs. MVC) should make any difference. – Craig W.

Hi - there is no error - the iframe window is just blank when looking at the MVC version. Also, there is no X-Frame-Options header being set - I checked that too, thanks. – Mark
@MarkTait how did you solve it? – Rolando

Have you tried this? Link below claims if the iframe's source site has the following css, it produces a blank iframe.

html{ position: relative; }

I've used iframes inside MVC apps before, so they do work. But, I've only used them within the same domain.

It looks like Microsoft.NET updated MVC to automatically write out a SAMEORIGIN X-Frame-Option header that would supersede any attempts you've made to add your own custom headers.

This other Stack Overflow answer gave me the solution:
