Link type "prerender"

The prerender keyword may be used with a link, a, and area elements. This keyword creates an external resource link.

The prerender keyword indicates that preemptively fetching and loading the specified resource in a hidden top-level browsing context is likely to be beneficial, as it is highly likely that the user will navigate to this resource. If the resource is navigated to, the user agent may replace the current browsing context with the one it loaded the specified resource in. If the user agent performs such a replacement, it should preserve the replaced browsing context's session history in such a manner that it is indistinguishable from the case where the navigation happens without replacement.

If the user chooses to navigate to this resource, the user agent may navigate the current browsing context to the specified resource.

The user agent may discard the browsing context corresponding to the prerendered resource if any of the following is true:

  • If the resource is not navigated to within a reasonable amount of time.
  • If the user navigates to some other resource from the current browsing context.
  • If the link element is removed from the document.
  • There is no default type for resources given by the prerender keyword.
