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

to avoid 404 error on NGINX

• create an empty image file (blank.gif)
• put it into images directory
• use following configuration:

Location ~* /apple.*.png$ { rewrite ^.+$ /images/blank.gif last }
