Works great if you prefetch the home page - where most visitors go to after entering the site via a search engine.IE9 only supports DNS prefetching (via "prefetch" rel too) but it's for DNS, not link prefetching like FF/Chrome so really doesn't make much difference.The code for Wordpress sites is a bit different - included examples at http://techlogon.com/2011/10/22/speed-up-a-wordpress-blog-with-prefetch Nice article, Chrome now includes this link prefetching via the rel of “prerender” rather than “prefetch” so you need to include both if wishing to allow prefetch on both browsers.

I've heard that Chrome and Safari and others are doing this and it doesn't require the rel=prefetch tag to be in the code. The browser just prefetches on its own. And if so, is this type of activity still ignored by javascript based analytics (such as google analytics)?

But what if you're streaming music, and don't want to use up additional bandwidth? Can the user turn it off? It’s an interesting capability, and I could see many uses for it.

As far as I can tell, neither Firebug's Net tab or the LiveHTTPHeaders extension 'see' the prefetch request, so it's hard to figure out just what resources have been pre-loaded.
