That's not possible. If one wanted to implement it, the logical way 
would be to do full regexp pattern matching on the domains. That has 
been suggested in the past, but I've always resisted it on the grounds 
that it's overkill.

For wpad, the browser will always append a domain, I think. Can you not 
just enumerate all the possible domains?

Agreed that DHCP would be  better way to do this, but also agreed that 
it don't work on firefox (mainly because Linux lacks an API to the DHCP 
system than firefox can use, and the standards for DHCP say you need to 
send DHCPINFORM packets from a privileged port, which makes doing so 
from process run by an ordinary user impossible.)
