regardless of what others say it is NOT a cloaking page or something cloaking software creates
if it were cloaking software creating that you would never see that page, you would see a real site, what you are seeing there is what google/yahoo would see if it were cloaked
that is created using a doorway page generator, which is a totally old school method of putting up thousands of pages quick and getting keyword results to other "real" sites
here is a pretty cool app for doing it -
http://www.doorway-wizard.com/ - but like I said it is a pretty old school method and doesn't work that well anymore, google is pretty quick to knock you down for it, and while the software I linked does do "cloaked" pages, they are not
true cloaked pages
what you see in the link you posted is a "doorway page"
