What does it mean when the apple-touch-icon.png was requested

Question

I know what the apple touch icon is, and I have seen an apple desktop before, so I can imagine what it would look like. I also know how to add an apple touch icon to my site

Answer 1

Many log investigate to find that: whatever you have specified paths to apple-touch-icon files in the , Safari will search these files at the domain's root when you add a bookmark/home screen shortcut:

/apple-touch-icon.png
/apple-touch-icon-120x120-precomposed.png
/apple-touch-icon-120x120.png
/apple-touch-icon.png

Yes, 2 times the same file (tried on an iPhone 6).
