You most definately need a proxy server or something along those sorts to generate logs, you will also need to invest into something called webtrands or cyfin to view those logs in a logical format.
The logs can get very large, so this is not something you would want to review by looking at them
You an either use Microsofts Proxy Services, or Novells Bordermanager with Proxy/caching services. The Novell product is more intuitive, however, you must chose which fits your environment. Don't buy the product based on hype, thats a bad investment.
