Several ways for asp.net to display its webpage icons

If you use IE7 or a browser with multiple tabs, you will surely find the personal icon at the front of the tab. How can this be done?

I have never quite understood it. By chance, my colleague told me several practices and posted them to share with you.

1.
Put an ico icon directly to the root directory of your website and name it favicon. ico. Favicon. ico should be a 256-colored 16 icon.

<Link rel = "Bookmark" href = "favicon. ico"> you can display your icons in favorites.
