You can't. Not really. But you might be able to fake it.

This is why you can't do what you are asking to be able to do: the
favicon "spec" is the the icon is in the root of the domain, unless
overridden by a element in the HTML document.

I have no idea how you might do this with .htaccess.

Have a look at this SO answer:
http://stackoverflow.com/questions/11227661/adding-favicon-through-a-htt
p-header
Here's a way you might be able to fake it:
1. Write a Filter (or you could do this with mod_rewrite I suppose)
2. Hook on the request for /favicon.ico
3. Examine the request headers for the REFERER (yes, it's misspelled)
4. Return the bits you want depending upon the value of that header
This might not work for e.g. PDF files, but it would work for HTML
files that don't specify their own elements. YMMV.
