My interpretation (and hopefully Nick will jump in here soon and clarify) is that he's trying to get some additional cross-zone sharing, over simply running a fresh Apache in each zone. > I think the mention of zone_enter() is what made me think take Nick's > question quite literally.

The "user" of a hosting company is the hosting customer, *not* the guy behind the web browser. Note also that (with no disrespect meant to Nick) a common newbie behavior is to latch onto some random interface and attempt to bend it to solve the problem at hand, whether or not it's the intended way to solve that problem. >> It's quite possible that the IP address alone is enough to determine >> which zone the server should run in, in which case you could probably do >> the zone_enter before the listen().

IIUC HTTP/1.0 still must be supported (die, > HTTP/1.0, die!). I don't know what the HTTP/1.0 deployment picture is like these days, but I'm pretty sure that an HTTP/1.0 browser can't get to my personal web pages, because I don't have dedicated IP addresses. Host: is the only way to tell my URLs from the next guy's. _______________________________________________ zones-discuss mailing list email@example.com
