hi i'd encourage you to look into mod_perl as it can be amazing in letting you get the most out of your hardware.
as far as running multiple unrelated perl apps using mod_perl- i think it happens every day! you just need to program them accordingly. also, you can use virtual hosts under apache 1.3.x too. if you use appropriate naming for db handles, there should be no confusion. i'd also suggest you take a look at Apache::DBI. i don't know what framework you're using, or how you will segregate the apps. it might be better to have them all running under one webserver, or maybe you will need to start up a few of them. there are many mod_perl application frameworks that may help you get up and running more quickly. i know HTML::Mason and CGI::Application pretty well, and i think either could do what you want it to. with mod_perl you can do pretty much anything you want, it's just how much time do you have to spend programming to get it to work as you'd like. with the frameworks, there's even less programming that you need to do. good luck. -----Original Message----- From: James.

( issue like database handler pollution etc which i know little about )
