            Bug ID: 194539
           Summary: Add support for <link rel=prefetch>
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Page Loading
          Assignee: webkit-unassigned at lists.webkit.org

<link rel="prefetch"> can enable a site to make its page load near-instantly very easily. Users respond strongly to faster loading pages, as detailed in the first footnote on https://instant.page/ (it’s often been reported that 100 ms less latency results in 1% more sales).

https://instant.page/ prefetches a page on mouseover/touchstart and can make web pages near-instant in just one minute of work. It was released three days ago and got great responses (1200 points and #1 on Hacker News, #1 on Product Hunt).

https://github.com/GoogleChromeLabs/quicklink prefetches links that are in the viewport. It was released two months ago and amassed 5900 stars on GitHub.

So <link rel="prefetch"> gives tremendous results and there’s demand for it.

Maciej Stachowiak told me on Twitter that “WebKit has code to support link prefetch, but it's not enabled on macOS or iOS”, which is a bummer.

Firefox got it in 2006, Chrome in 2010, IE in 2013. Safari is the only one missing on it.
