For a long time, IIS already supported Favicon file by just add a 16x16 images with the name favicon.ico in the root of the application.
However, I only see the favicon file support in the Website, but not in the Application.

From the image above, if i keep the favicon.ico in Website, it will applied even for the Application under the Website.
Question: How can I add a different favicon for Application that differently with the Website?
