Is there a way to clear the favicon/apple-touch-icon cache for mobile Safari? The "delete all website data" button in settings doesn't do it.

(Safari appears to cache website icons aggressively for the "Add to Bookmarks"/"Add to Favorites" functions, but not for "Add to Home Screen". I'm interested in the former.)

I've managed to refresh it by loading ./apple-touch-icon-precomposed.png, but I only had apple-touch-icon.png in my main folder and had deleted the outdated precomposed one, so I believe you have to go to the original address that was stored in iOS Safari's cache.

It could be any of the following addresses, which are recommended by Apple Documentation on Web Applications:

  • apple-touch-icon-precomposed.png
  • apple-touch-icon.png
  • touch-icon-ipad-retina.png
  • touch-icon-ipad.png
  • touch-icon-iphone.png

And don't forget to compress your PNG to save bandwidth!
