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:
- What happens if you try and prefetch a page with streaming data, like Youtube? Will the video start buffering?
- 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.
