Overview

How it works: When given a domain w/o a path, try to find /favicon.ico If not found (or given a path), load the home page and search for one of:

  • <link rel=“shortcut icon” href=“example.com/myicon.ico” />

  • <link rel=“icon” type=“image/vnd.microsoft.icon” href=“example.com/image.ico” />

  • <link rel=“icon” type=“image/png” href=“” />

  • <link rel=“icon” type=“image/gif” href=“” />

If given a path, and the above didn’t work, retry on the domain’s index page
