A new report says that proxy server usage by Internet service providers
(ISPs) has increased by 13 percent since April 1999, reaching 16.99 percent
on Sept. 13.
Internet tracking and traffic analysis firm WebSideStory said that as a result, Web

And that’s certainly significant if your
site revenues are largely based on CPM ad revenues.
More details are available at WebSideStory’s StatMarket.com Web site based on data
continuously updated in real time.
Proxy caching appeals to ISPs because it reduces bandwidth requirements by
eliminating the need to “pull” remote content repeatedly, each time an

“This proxy server problem is only going
to get worse; some of your most valuable users will be hidden behind a proxy
server if you rely on log files.”
