Prerender and prefetch support

Use prerender and prefetch in Internet ExplorerÂ 11 to improve your website's navigation.Â Prerender (also called preload) specifies a webpage to be loaded (rendered) in the background while the user reads the current page and prefetch identifies resources to be downloaded in the background. Because both features download content before it's needed, the resources are instantly available when needed

Link prefetching - Wikipedia

Link prefetching allows web browsers to pre-load resources. This speeds up both the loading and rendering of web pages. Prefetching was first introduced in HTML5. Prefetching is accomplished through hints in web pages. These hints are used by the browser to prefetch links. Resources which can be prefetched include: JavaScript, CSS, image, audio, video, and web fonts. DNS names and TCP connections

Resource Hints

Resource Hints allow us to help the browser find the resources it will need, and download them ahead of time for better performance. For modern websites, optimizing speed requires more than just minimizing the initial download size and critical rendering path. We can optimize the loading of resources by resolving and prefetching them as early as possible. â€œPrefetchingâ€ is simply the act of startin

DNS Prefetching

Probl em DNS resolution time can lead to a significant amount of user perceived latency. The time that DNS resolution takes is highly variable. Latency delays range from around 1ms (locally cached results) to commonly reported times of several seconds. Solution DNS prefetching is an attempt to resolve domain names before a user tries to follow a link. This is done using the computer's normal DNS re
