So with IE9 around the corner, the favicon is evolving as along with pinning and such we need 64x64, 32x32, 24x24, 16x16 favicons.
This makes the actual favicon quite a bit larger (file size). Is there some way we can display only 16x16 to all browsers and just serve the larger favicon file to IE9 users?
Conditional comments for ie 9 would ive the only way for ie 9 to have a unique favicon. Because there is a way to make a specific favicon for all ie versions
But I do.not recall how.
I found It useful to use the Wikipedia article on favicons.
I hope that helped
