-# Echo Server
+# Static Response Server
 
-A very simple HTTP echo server with support for web-sockets.
+A very simple static HTTP server with support for web-sockets.
 
-- Any messages sent from a web-socket client are echoed.
+- Any request, independent of content, will always return a static body and content type.
+- Any message sent from a web-socket client will be replied with same static response.
 - Visit `/.ws` for a basic UI to connect and send web-socket messages.
-- Requests to any other URL will return the request headers and body.
+- The `CONTENT_TYPE` and `CONTENT_BODY` defines response's content type and body.
 - The `PORT` environment variable sets the server port.
 - No TLS support yet :(
 
 To run as a container:
 
 ```
-docker run --detach -P jmalloc/echo-server
+docker run --env CONTENT_TYPE=application/json \
+           --env CONTENT_BODY='{"upstream": "production"}' \
+           --detach -P pagarme/static-response-server
 ```
 
-To run as a service:
+Also works great with `docker-compose`:
 
-```
-docker service create --publish 8080 jmalloc/echo-server
+```yaml
+services:
+  production:
+    image: pagarme/static-response-server
+    environment:
+      - PORT=8080
+      - CONTENT_TYPE=application/json
+      - CONTENT_BODY={"upstream":"production"}
+    ports:
+      - "8080:8080"

+  sandbox:
+    image: pagarme/static-response-server
