That is not exactly true and while I normally would not have bothered
to correct that, but I had to answer quite a few customer questions
yesterday, so here we are. Akamai/Nominum Cacheserve and Akamai/Xerocole
AnswerX are not affected by this. We had limits in the software for this
in the Cacheserve case from day one. Would appreciate if you could
correct that in the article.

So long
