The problem comes from a shortcoming in the http protocol itself; the base site name is not forwarded to the host when the http query is made. This is because the CERN/UIUC folks way back a few years ago, when they invented http thought that noone would ever want to do that, I guess... Again, nothing you can do on the server end will help except for multiple IP addresses!!! (well, you can kluge it like a lot of providers do with http://provider.name/~site but it sounds like you don't want to do that; another way involves CNAMEs and a chooser page but that's a kluge too). Fixing this would require EVERY BROWSER IN THE WORLD to be fixed; there is room in the http protocol for that request (proxies use it) but the default is to not do it... A revision to the http protocol would have to be backward compatible for a few years, anyhow, so the fix would be long in coming. Multiple IP addrs aren't really a big problem if you're a provider. They would be if you pay for each one, or aren't on a routed subnet. I have a freebsd apache server with 19 aliases on it now; it still works just fine, though our request rate is still fairly low (about 100/hr total files on average over January; most requests were for two of the (sub)-sites. Samples -- www.ci.diamond-bar.ca.us, www.turkeyrack.com (really :-), www.macom-phi.com, and several others. These are on a P120 with 64mb of ram and "lots" of disk, primarily running inn and httpd; also serving as a primary or secondary name server for a bunch of domains.. Just on general principles, we are planning to split the web and news services; a P120 can easily keep up with a T1 doing all of this so we don't really need to split them up (but it takes *lots* of ram to keep the response times reasonable, especially if you want to run X on the console too). -- Pete
