Copied form a quick Google search:
The page employs code to inflate the number of times ads are loaded.
Normally when a page is loaded its code and all ads on the page are
stored in the browser cache. If the page is reloaded, the browser
checks to see if anything has changed on the page. If there are no
changes, the page and ads are loaded from the cache which is faster.
Usually advertisers pay web page owners for every time their ad is
loaded into a browser. Some page operators put code in their page to
confuse the browser into loading ads from the web site every time the
page is accessed rather than from its cache. This is a rip off from
the advertisers's point of view, because it artificially inflates the
number of times that the ad would have been loaded. This code is
called the "Cache-busting LUBID bug".
