dns-prefetch. Anyone familiar?
Hi colleagues and friends.

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

anyone give a summary on this and save me a job sniffing browser traffic? (Which I can't do from my work PC for usual corporate network pain reasons <groan>).

I guess I'm after 3 things:

- Does this block download in any subtle way?
- Is this FF only?
- Does it force the browser to DNS lookup when it encounters the link (or only when it's DNS cache is empty/stale?)

DNS lookups can be pretty frightful in some parts of the world, so I'm looking to see what we can do to alleviate it.

BR
Neil
