Nginx try_files for separate server

# Directives to send expires headers and turn off 404 error logging.
location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
  expires 24h;
  log_not_found off;
  try_files $uri $uri/ @production;
}

location @production {
  resolver 8.8.8.8;
  proxy_pass http://www.livesite.com/$uri;
}

@jeremyfelt @TheLastCicada Any reason there's a $uri $uri/ in try_files, instead of just $uri?

No good reason I can think of - especially for the file types in question.
