Has anybody managed to get the current re-write rules ported over to nginx.

The back end works fine so long as the define browse rule is commented out in the nginx.config

The back end is blazingly fast on nginx running on a single core cloud instance. Which is what I wanted; improves your pages peed ranking with google.

I can do all the blocking rules using config picked up off the net for that. but the re-writes are not letting the page display.
