dns-prefetch. Anyone familiar?

[p83822]

OK

So I had a test page with some 20 discrete prefetches in the head and 1 image in the body.

- IE does not prefetch, as Pat indicated
- Chrome does prefetch and it does seem to do it asynchronously (as per http://dev.chromium.org/developers/desig...refetching )
- Safari does not prefetch

However I just could not seem to get FF3.6 to do it (network.dns.disablePrefetch setting was not set i.e. I had default settings)

I tried disabling FF cache using network.dnsCacheEntries = 0.
I tried restarting FF
I tried clearing the windows DNS cache
...and all the combinations thereof.
