Updating favicons

I was working on a site and testing in Firefox, and after changing the favicon (the little icon that shows up before the address and with the tab) seemed to be cached. Refreshing the page didn't clear it up.

After some googling, I found this blog entry which contained a comment that answered my question.

To refresh a favicon, do the following:

• Crack open the html with View Page Source
• Find the address of the favicon link, usually in a tag with <link rel="shortcut icon"...
• Put the full address of the favicon in the address bar (e.g. http://www.mysite.com/images/favicon.ico)
• Hit the refresh button to be sure

That's it...should be updated now for any visit to the site.
