Prerender/Prefetch Test Page

Clicking either button below will add a <link rel="prerender"> or <link rel="prefetch"> tag (pointing to a random website from an embedded list) to the head of the document.
This should demonstrate that, in Chromium, rel="prefetch" network activity is shown in the Developer tools' Network tab, but rel="prerender" related network activity is not.
You can view the page source here; see also the Chromium ticket.
