+# Plain HTTP 1.1 upstream
+
+APIcast --> upstream plain HTTP 1.1 upstream
+
+APIcast configured with plain HTTP 1.1 upstream server equipped with traffic rely agent (socat)
+
+## Run the gateway
+
+Running local `apicast-test` docker image
+
+```sh
+make gateway
+```
+
+Running custom apicast image
+
+```sh
+make gateway IMAGE_NAME=quay.io/3scale/apicast:latest
+```
+
+Traffic between the proxy and upstream can be inspected looking at logs from `example.com` service
+
+```
+docker compose -p plain-http-upstream logs -f example.com
+```
+
+## Testing
+
+`GET` request
+
+```sh
+curl --resolve get.example.com:8080:127.0.0.1 -v "http://get.example.com:8080/?user_key=123"
+```
+
+`POST` request
+
+```sh
+curl --resolve post.example.com:8080:127.0.0.1 -v -X POST "http://post.example.com:8080/?user_key=123"
+```
+
+## Clean env
+
+```sh
+make clean
+```
