Prefetching is one of the new standards that make up HTML5. You can add it to tags like this:

<link rel="prefetch" href="/images/big.jpeg">

My questions:

  1. What happens if you try and prefetch a page with streaming data, like Youtube? Will the video start buffering?
  2. Does it matter what the content is (Flash vs HTML5 video for example)? I ask this because this FAQ mentions that only HTTP/S will be prefetched.

  • Ok, since no one is answering I guess it is research time. – Mikle Jan 03 '13 at 16:34
  • I think that it is up to the browser implementation. I had made some research in the pas and this is where it led me. – Jimmy Kane Jan 03 '13 at 16:50

    @JimmyKane Thanks for the answer. I guess you are right and this is (unfortunately) not standardized. I'll leave the question open and maybe in the future there will be a definite answer. – Mikle Jan 03 '13 at 17:26
