The proxy middleware is not forwarding requests #1808
Description
Issue Description
The proxy middleware is not forwarding requests
Expected behaviour
Middleware should be called to forward request to the another echo instance
> GET http://localhost:8081/resource/1 < HTTP 200 > PUT http://localhost:8081/resource/1 < HTTP 200 Actual behaviour
Middleware is not called and I'm getting back a 405 status code (method not allowed)
> GET http://localhost:8081/resource/1 < HTTP 405 > PUT http://localhost:8081/resource/1 < HTTP 200 Steps to reproduce
GET http://localhost:8081/resource/1 Working code to debug
