Not all headers are created equal and the way we turn them off within the Microsoft stack differs. Let’s recap on the ones we saw earlier on:

Server: The web server software being run by the site. Typical examples include “Microsoft-IIS/7.5”, “nginx/1.0.11” and “Apache”.
X-Powered-By: The collection (there can be multiple) of application frameworks being run by the site. Typical examples include: “ASP.NET”, “PHP/5.2.17” and “UrlRewriter.NET 2.0.0”.
X-AspNet-Version: Obviously an ASP.NET only header, typical examples include “2.0.50727”, “4.0.30319” and “1.1.4322”.
X-AspNetMvc-Version: Again, you’ll only see this in the ASP.NET stack and typical examples include “3.0”, “2.0” and “1.0”.
