The DNS server is a system wide setting, all applications depend on the system, which depends on the DNS. the proxy settings are for an application. This is picking nits. I initially was hoping to use DHCP, but it doesnt offer the cross platform and lifetime flexibility that DNS does and its less widely deployed. Another fundamental issue here is if you buy into the service location protocol ideas. I do. They are trying to solve the problem of "how do I use a standard method to look up arbitrary services on a network". Granted, by following their DNS recommendations ( which is only one of many ways to advertise services in their world ), its not perfect. In time, I hope that we could support their multicast discovery protocol as well. I suppose I could have specified that in the draft, but since the rest of the serverloc stuff is so new, and virtually undeployed as of yet, I figured this gives us a solution to a big problem, today, with protocols and APIs software implementors in the realm of the 'world wide web' are commonly using. ----------------------------------------------------------------------------- Josh Cohen Netscape Communications Corp.
