Secure WebSockets over SSL/TLS
To prevent man-in-the-middle attacks between server and client, it is strongly recommended to use the WSS protocol, to send encrypted TCP messages. This is the equivalent of using HTTPS instead of HTTP.
Setting up NGINX
We will use NGNIX as a reverse proxy that forwards all incoming requests to the Spring Gateway MS. We will configure the proxy to listen to port 443 which is the default port for secure connections in both HTTPS/WSS.
