I am using the following:
<link rel="shortcut icon" href="/images/favicon.ico" />
It is a true 'ico'. When I visit http://mydomain.com, the icon loads. But when I visit the 'www' subdomain: www.mydomain.com...it won't load. Any ideas what is going on?
This sounds like a configuration issue on your end which we can't solve without more information. Have you tried using an absolute URL instead of a relative one?
Example:
<link rel="shortcut icon" href="http://mydomain.com/images/favicon.ico" />
Perhaps the first slash in
href="/images/favicon.ico"is causing a problem?
Have you tried
<link rel="shortcut icon" href="images/favicon.ico" />
? What is the directory structure for www subdomain? Can you access other image files using the absolute path?
Fireworks often picks up the favicon.ico file automatically without any code, so long as it is the same folder as the document. Try moving your file up a level to avoid referencing issues.
