Ask HN: Why doesn't Safari support link prefetching?

4 points by anderspitman 7y ago

See [0]. This feature has been around so long I'm assuming it must be a deliberate decision, but a quick search hasn't yielded any information. [0] https://caniuse.com/#feat=link-rel-prefetch

Because they prefetch without any reference to said attribute? Or at least there used to be a setting on the mobile version that was on by default that enabled that.

  That's interesting. I'll have to do some tests to see if that's still the case.

I'm in the same boat. It's weird that WebKit supports `preload`, which is a newer spec, but they never mention `prefetch` support anywhere: https://webkit.org/status/#?search=preload https://webkit.org/status/#?search=preload I found these neglected issues in WebKit Bugzilla: - "implement Link: header" https://bugs.webkit.org/show_bug.cgi?id=51940 https://bugs.webkit.org/show_bug.cgi?id=51940 - "Add support for <link rel=prefetch>" https://bugs.webkit.org/show_bug.cgi?id=194539 https://bugs.webkit.org/show_bug.cgi?id=194539
