prefetch

Summary

Prefetches frame content so a later navigation can reuse the response. By default this fetches HTML and discovers external JavaScript, CSS, and explicit image and font preloads for <link rel="prefetch"> hints. Responses use the browser HTTP cache; even uncacheable HTML can reveal cacheable assets. Pass prefetch to run() to change this behavior. Cross-origin URLs, the current untargeted page, and browsers where Remix doesn't handle navigations are skipped.
