Multiple Domains, Single IP, Single Server

I have searched and searched. I have two domains directed at a single gentoo VPS instance. I have two wordpress installs in two folders…

~/example1.com/htdocs/
~/example2.com/htdocs/

the first is a business production site, and the second is to play around on and see if wordpress can do some more extreme things; test stuff out before it goes live.

I am using lighttpd and my rules are as follows:

$HTTP[“host”] =~ “(^|\.)example1.com” {
server.document-root = “~/example1.com/htdocs”
$HTTP[“host”] == “mail.example1.com” {
server.document-root = “~/mail.example1.com/htdocs”
}
$HTTP[“host”] == “admin.example1.com” {
server.document-root = “~/admin.example1.com/htdocs”
}
}
$HTTP[“host”] =~ “(^|\.)example2\.com$” {
server.document-root = “~/example2.com/htdocs/”
}

When I set a static file in each root (i.e. helloworld.html), it goes to the right root. but for some reason when i visit example1.com or example2.com I am directed to example1.com.

lighttpd says it is changing the address after fcgi is called, so i think it is index.php calling something that directs it to the first install. any ideas?
