I am totally fine with just making an additional server {} block instead of http {}

This is pretty much the only configuration option I'd want to change: client_body_temp_path /var/mogdata/.tmp;

would this work? I guess the more I think about it I don't care where it puts the temp files... I just know that /var/mogdata/.tmp works nicely for the mogilefs stuff.

server { access_log off; listen 7500; server_name localhost; client_body_temp_path /var/mogdata/.tmp; charset utf-8; location / { root /var/mogdata/; dav_methods put delete mkcol copy move; dav_access user:rw group:rw all:r; create_full_put_path on; } }
