Description Alexey Proskuryakov 2010-11-02 11:32:26 PDT

It's possible to specify a hostname instead of URL for DNS prefetch using double slash:

<link rel="dns-prefetch" href="//www.spreadfirefox.com">

There is no code in WebCore to that effect - instead, this is parsed as URL, and magically works for HTTP. This is fragile, and can fail for other main document schemes.
