Can we add more examples ?

one example use case may be doing nginx reverse proxying using WebSockets where the encrypted ips are passed in the header when the first response is sent from the server to the client and further the next following requests from the same client come with encrypted ip in the header, which nginx decodes and then routes the request to the correct downstream server with the ip same as we got after decrypting the (encrypted)ip from the header in the request (on load balancer or nginx).

• In the above case we want to have the encryption logic on the server side and decryption logic on the load balancer (nginx) side.

Review the repository's existing examples and the described nginx reverse-proxy flow involving WebSockets, encrypted headers, a server, and a load balancer. Add a focused example showing server-side encryption and nginx-side decryption and routing, with the completed example matching that use case.
