We've got multiple web servers configured in a cluster using Microsoft's Web Farm Framework. One of the things I like to do to help debugging is to create a header in IIS that identifies the server that handled the request. Unfortunately when I try to do this, WFF sets the headers to the same value on all the servers. Is there a way around this?

I tried looking into using skipDirectives, but I can't find any documentation on it (other than a little bit showing how to use it to skip directories and bindings).

If there is documentation on this, please link to it! I would like to be able to read up more on it in case I need to do other things as well.
