That's a lead, but this still makes the same number of requests, and
also messes the statistics (in this case, France getting 6% more
hits).

Maybe this is better done at the HTTP level but I'm in favour of a
less abusive way to poll the news.

It's be interesting to know if planetplanet supports those headers,
though, just in case :)
