== Proxy Server Configuration

When using a proxy server, it is important to ensure that you have configured your application properly.
For example, many applications have a load balancer that responds to request for https://example.com/ by forwarding the request to an application server at https://192.168.1:8080
Without proper configuration, the application server can not know that the load balancer exists and treats the request as though https://192.168.1:8080 was requested by the client.
For example, many applications have a load balancer that responds to request for https://example.com/ by forwarding the request to an application server at https://192.168.0.107
Without proper configuration, the application server can not know that the load balancer exists and treats the request as though https://192.168.0.107:8080 was requested by the client.

To fix this, you can use https://tools.ietf.org/html/rfc7239[RFC 7239] to specify that a load balancer is being used.
To make the application aware of this, you need to configure your application server to be aware of the X-Forwarded headers.
