[3] 859177 – Investigate link rel=subresource prefetching ( 版) https://bugzilla.mozilla.org/show_bug.cgi?id=859177
The intent of the subresource attribute on <link> was to prefetch a resource during a browser’s idle time. After a browser downloaded a page, it could then pre-download resources such as other pages so that when they were requested by users, they could simply be retrieved from the browser cache.
