Yep. Prefetch != prendering. Prefetch only fetches the single resource, and is meant as a "post load" hint. Whereas prerendering fetches the entire page, and all of its assets.
Does prerendering execute JavaScript or only load assets?
Thanks for the clarifications.
But isn't it really a matter of time before the `prefetch` and `prerender` options get ignored? Some rogue sites are just going to mark all their links with `prerender`. This is almost akin to the `meta keywords` that were abused for a long time, and then all search engines started ignoring it.
There's probably a reason most browsers have been so slow to adopt it - especially Opera. Perhaps the reason Chrome is the only browser supporting it is that Google can leverage the web crawlers to scan for malicious use of the attributes.
