ASP.NET MVC: Programmatically set HTTP headers on static content
<p>I have an ASP.NET application with a filter wired up in <code>RegisterGlobalFilters</code> that performs the following:</p>

<pre><code>public class XFrameOptionsAttribute : ActionFilterAttribute
{
    public override void OnResultExecuting(System.Web.Mvc.ResultExecutingContext filterContext)
    {
        filterContext.HttpContext.Response.AddHeader("X-FRAME-OPTIONS", "SAMEORIGIN");
    }
}
</code></pre>

<p>Looking in Fiddler, I can see that views returned from the webserver include this header.  Static files however, such as JavaScript do not include this header in the HTTP response.</p>

<p>How do I get ASP.NET MVC to also apply this filter to any static files the web server returns?</p>
