Sample Parameters in an NGINX Configuration

Note: These parameters are not intended to be a complete NGINX proxy configuration, but should be considered as a starting point/checklist of viable parameters that IFS Applications depend on. Other NGINX parameter settings and values should also be considered based on customer requirements.

# If we receive X-Forwarded-Proto, pass it through; otherwise, pass along the
# scheme used to connect to this server
map $http_x_forwarded_proto $proxy_x_forwarded_proto {
  default $http_x_forwarded_proto;
  '' $scheme;
}

# If we receive X-Forwarded-Port, pass it through; otherwise, pass along the
# server port the client connected to
map $http_x_forwarded_port $proxy_x_forwarded_port {
  default $http_x_forwarded_port;
  '' $server_port;
}

# If we receive Upgrade, set Connection to "upgrade"; otherwise, delete any
# Connection header that may have been passed to this server
map $http_upgrade $proxy_connection {
  default upgrade;
  '' close;
}

# Set appropriate X-Forwarded-Ssl header
map $scheme $proxy_x_forwarded_ssl {
  default off;
  https on;
}

# Set Headers
proxy_set_header Host $http_host;
proxy_set_header Upgrade $http_upgrade;

# Disable the verification of the proxied HTTPS server certificate (eg: MWS certificate). 
# Note: this might violate the corporate securtiy policy of the customer.

# Set the timeouts depending on the usage of the IFS Applications.
