eSearch usedomain='true' command - Coded Value Domains not available in REST URL.

Sorry if this is not the exact place to get an answer, but I cannot find information on it anywhere and can't think of anywhere else to ask the question.

I'm working with the eSearch 3.4 widget and its working out great, except that I cannot take advantage of the usedomain command because my domains are not carrying over into my REST URL. I have a duplicated web application hosted on Amazon in which I 'can' see the domains in the REST URL. For some reason when I'm publishing a service inside of our firewall I cannot detect them. I tried overwriting the service but to no avail.

Can someone please shed light on this for me or guide me toward documentation that would help me?

Thanks,
Scott
