## Proxy Authentication
See above for no authentication (`--no-auth`) and basic authentication.
To delegate authentication to a proxy, use the `--proxy-auth-username` flag. The specified header name, for example `X-Forwarded-User`,
must be present in the request headers and specifies the username. Basic authentication is disabled when this flag is set.
Warning: rest-server trusts the username in the header. It is the responsibility of the proxy
to ensure that the username is correct and cannot be forged by an attacker.

Enhancement: Add support for proxy-based authentication
The server now supports authentication via a proxy header specified with the --proxy-auth flag (e.g., --proxy-auth=X-Forwarded-User).
The server now supports authentication via a proxy header specified with the `--proxy-auth-username` flag (e.g., `--proxy-auth-username=X-Forwarded-User`).
When this flag is set, the server will authenticate users based on the given header and disable BasicAuth.
Note that --proxy-auth is ignored if --no-auth is set, as --no-auth disables all authentication.
