WWW servers can issue a "redirect" to a different URL. Anybody can hack this up with something like Apache by adding index.cgi to the index page possibilities and then enabling .cgi as an extension to automatically run a CGI script which could issue the redirect in the HTTP headers instead of emitting an HTML document. The CGI script would only need to be a simple table lookup similar to what a Cisco's SSP does. Of course their needs to be something more intelligent (like BGP to continue the analogy) that builds and maintains the lookup table based on some sort of heuristics.
Isn't IBM doing some sort of fancy load redistribution for the WWW servers its running for the 1996 Summer Olympics? I seem to recall they were determining the "closest" server via a technique called "ping triangulation", whatever that is. Christopher E.
