In previous blog posts, we saw how to proxy requests to an ASP NET Core application using Nginx. We saw that request headers also can be proxied with proxy_set_header In order to ease development, we need to be able to debug the values to verify that they are what we expect.
Today we will see two methods to inspect the proxied requests.

When proxying a request to an underlying server, it is necessary to validate its SSL certificate. For example, if we have a process running on https://localhost:5001, we can configure Nginx to validate the certificate used by localhost:5001. But if we miss one step, we face the common error 502 Bad Gateway returned by Nginx. Today we will see two scenarios where we can face the error and how to fix them.

Today we will focus on how to setup SignalR to work with WSS, Websocket secure and how we can authenticate the user requesting to connect to our SignalR hub via Websocket.
