We tend to have the domain assigned to each computer by the DHCP server differ depending on the machine's address range. This means wpad.<domain> is different for each ip range so you can have static wpad files. However, I was hoping to have them all hosted on one apache server using a vhost but it turns out that some but not all of the browsers (firefox and some versions of IE) don't load http://wpad.<domain>/wpad.dat. Instead they do a DNS lookup, then download http://<wpadserverip>/wpad.dat which means you can't use vhosts. This is a real PITA. For now, we've got the wpads on different servers, but a PHP-driven wpad.dat was my next solution. Gavin
