So far nothing I've seen would > allow a single URL to be used to access the "nearest" server. 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. > Until > something like that exists It exists right now.
