RequestFiltering - Server Level

Hello..

I have rules and other features configured at the website level for request filtering. I'd like to move these to the server level so it covers all websites configured within IIS.

I added a couple rules, etc., to the server level Request Filtering, and did a search but I can't locate the file which stores this information.

Where does IIS store the request filtering configuration for items in the server level?

Thanks..

EDITED: This is on a Windows2k8R2 server running IIS 7.5
