[cups.general] X-Forwarded-For

[Michael Sweet]

This configuration isn't currently supported by CUPS, mainly because you used to be able to use implicit classes with CUPS browsing on the clients to have the clients do their own load balancing...

On the client machines you can setup classes that point to each server queue, and then the clients will round-robin between the two, preserving the client address and username.
