reverse proxy root folder only

[starmonche]

I have an nginx serverset up and I'm looking for a way to only reverse
proxy the contents of the root folder. I'm using a location regex with a
list of the files in root that are allowed and then a second catch-all
location that goes nowhere but there must be an easier or cleaner way to
do this.
