 Nginx Proxy Config
 ------------------
 
 
 Set the following properties in your ``/etc/nginx/proxy.conf`` so it does not
 timeout during large pushes.
 
 .. code-block:: nginx
 
     proxy_redirect              off;
     proxy_set_header            Host $http_host;
 
     ## If you use HTTPS make sure you disable gzip compression
     ## to be safe against BREACH attack.
     gzip                        off;
 
     # Don't buffer requests in NGINX stream them using chunked-encoding
     proxy_buffering             off;
 
     ## This is also required for later GIT to use streaming.
     ## Works only for Nginx 1.7.11 and newer
     proxy_request_buffering off;
     proxy_http_version 1.1;
 
     ## Set this to a larger number if you experience timeouts
     ## or 413 Request Entity Too Large, 10GB is enough for most cases
