Hi,

I try to understand how to use kong to interact with websocket application.

1. create service and ingress to access external [websocket.org](http://websocket.org)

> * * *
> 
> kind: Service  
> apiVersion: v1  
> metadata:  
> name: proxy-to-websocket  
> namespace: default

> port: 80  
> type: ExternalName  
> externalName: [websocket.org](http://websocket.org)
> 
> * * *

apiVersion: [configuration.konghq.com/v1](http://configuration.konghq.com/v1)  
kind: KongPlugin  
metadata:  
name: transform-request-to-websocket  
config:  
remove:  
headers: host

1. Run

> curl -X GET --url [http://100.22.4.25:31329](http://100.22.4.25:31329) -H “host: [echo.websocket.org](http://echo.websocket.org)” -H “Connection: Upgrade” -H “Upgrade: Websocket” -i -N

404 Not found

1. Run

> curl -X GET --url [http://100.22.4.25:31329](http://100.22.4.25:31329) -H “host: [echo.websocket.org](http://echo.websocket.org)”

No error

Do I miss something when config service and ingress?

Thanks.
