Have you ever noticed that IIS tends to brand every HTTP response with the header X-Powered-By: ASP.NET - it will do this even if your site is not powered by ASP.NET!

Here's how to remove it on IIS 7 / 7.5:

  1. Open Server Manager and select the server name under Internet Information Services (IIS) Manager
  2. Double click HTTP Response Headers
  3. Remove the X-Powered-By header if it exists
IIS 7.5

Here's how to remove this header on IIS 6:

  1. Open up the IIS Management Console
  2. Right Click on a Web Sites and select Properties
  3. Click on the HTTP Headers Tab
  4. Under Custom HTTP Headers click on X-Powered-By: ASP.NET and click Remove
