Checking Websockets with curl

Naturally the curl command doesnt allow the ability to curl websockets. example:

$ curl --include \
       --no-buffer \
       --header "Connection: Upgrade" \
       --header "Upgrade: websocket" \
       --header "Host: testexample.com:80" \
       --header "Origin: http://testexample.com:80" \
       --header "Sec-WebSocket-Key: SGVsbG8sIHdvcmxkIQ==" \
       --header "Sec-WebSocket-Version: 13" \
       http://testexample.com:80/

You can copy this and replace testexample.com with the hostname of your choice and you’ll see all the websocket data you need.
