# Config for Nginx to act as a front-end for Riak
# The main goal is to proxy all GETs directly to Riak, and disallow anything else (POST, PUT, etc)
# Also, disallow use of the map/reduce query links (i.e. /riak/bucket/key/_,_,_)

# Config is in /etc/nginx/sites-available/default or somewhere like that

# Set up load-balancing to send requests to all nodes in the Riak cluster
# Replace these IPs/ports with the locations of your Riak nodes
