Changing website favicon dynamically

Question

I have a web application that\'s branded according to the user that\'s currently logged in. I\'d like to change the favicon of the page to be the logo of the private label,

Answer 1

The only way to make this work for IE is to set you web server to treat requests for *.ico to call your server side scripting language (PHP, .NET, etc). Also setup *.ico to redirect to a single script and have this script deliver the correct favicon file. I'm sure there is still going to be some interesting issues with cache if you want to be able to bounce back and forth in the same browser between different favicons.
