Sorry, shouldn't have posted that shortly before a near-7-hour journey. Just digesting the replies now. >> I think the mention of zone_enter() is what made me think take Nick's >> question quite literally.

To have it happen per-request in the server would imply an enormous overhead, because it's a complete misfit to the Apache architecture. CGI could perhaps do it in a similar manner to the existing setuid wrapper, but that's a lesser solution to a less-interesting problem. > 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. That may indeed be the case. Though I should add, my newbiedom applies to Solaris kernel goodies, not to Apache or web-serving (guess it's time to attach my apache book .sig:-) I'm exploring (or, if you prefer, latching on to) the possibility of a strong solution to a long-standing problem. > -- Nick Kew Application Development with Apache - the Apache Modules Book http://www.apachetutor.org/ _______________________________________________ zones-discuss mailing list firstname.lastname@example.org
