It might be worth thinking about the problem from the other end. From a web site owner's perspective, caching is a major annoyance. Here are the arguments you may encounter from a web site owner or web developer: 1. It interferes with content in many cases (web site visitors may see cached pages instead of current content). I know cache products claim this doesn't happen, but it has, and often. 2. The website owner loses information on how many visitors are coming to the site. 3. The website owner loses the demographics on where visitors are coming from, and especially the number of unique visitors. (It's not helpful to know that one cache engine visited, if that cache engine equated to 10,000 visits in an hour). 4. Banner advertising may or may not display properly when caching is involved, thereby costing the website money. 5. There's NOTHING in it for the website owner, other than the possibility that SOME pages might display faster for SOME users. If folks running networks really think website designers and owners should care about caching, then there needs to be some sort of benefit (perhaps paid in dollars) to those affected. Otherwise, there's little reason for them to care. -- ----------------------------------------------------------------- Daniel Senie [email protected] Amaranth Networks Inc. http://www.amaranth.com
