# Upstream mTLS (Proxy Presents Client Certificate)
#
# Plain HTTP from clients; the proxy presents a client
# certificate to the upstream backend, which requires
# mutual TLS authentication.
#
#   Client -> HTTP -> Praxis :8080 -> mTLS -> Backend :9443
#
# Usage:
#   cargo run -p praxis-proxy -- -c examples/configs/protocols/tls-mtls-upstream.yaml
#   curl http://localhost:8080/
