Nginx reverse proxy with rate limiting

ratelimit.nginxconf

#
# This will ratelimit requests to 10/s
# It will allow up to 128 requests to connect, make their request, and then delay the response
# On the client side, this will appear to be "hung", until one of the 10 slots opens up, at
# which point it will proxy your request
#
# If more than 128 requests are queued, any after that will immediately be returned with an
# error
#
