Out of curiosity: Does prefetch have a positive effect on (html) resources with max-age set to 0?
Aren't cache headers respected?

Prefetch has special caching semantics and allows using the resource once within 5 minutes (or something like that) even if it has expired per its max-age.

Thanks! Are you aware of any document describing that behavior? Could not find it here: https://w3c.github.io/resource-hints/#prefetch

@robin-drexler @cramforce indeed, works in Blink-based browsers.. Not 100% on other browsers. This is an un-specced corner of the platform, see: w3c/preload#97
… ti.to Prefetches the main doc and known sub resources whenever a doc finishes loading. On mouseover and click of the purchase button, preconnects to ti.to and other origins that ti.to uses to flatten the connection tree.
