prefetch resources

Postby piky » Sun Dec 23, 2012 10:39 pm

Hello,

I have a question related to 'prefetch' value of the rel attribute on a link element.

http://www.whatwg.org/specs/web-apps/cu ... e-prefetch
says: "prefetch..keyword creates an external resource link."

external resource link = links to resources that are to be used to augment the current document

If I understood this correctly it referees to: images, style sheets, video files, audio files

If so, then why lots of developers try to prefetch external resources that implies navigation
(hyperlinks) ?
e.g. <link rel="prefetch" href="http://www.example.com/page2.html">

Am I getting it wrong or they are making a mistake ?

Regards,
Piks
