terminate_http2_post.yaml

# This configuration terminates a POST request and sends the POST payload upstream.
# It can be used to test TCP tunneling as described in
# https://envoyproxy.io/docs/envoy/latest/intro/arch_overview/http/upgrades
# or used to test POST directly, by running `curl -k -v -x 127.0.0.1:10001 https://www.google.com`
