Bug 2224651

curl is not currently compiled with websockets support - it would be great if it could be compiled with websockets support.

websockets support was added in curl 7.86.

Reproducible: Always

Steps to Reproduce:
1. curl 'wss://websocketstest.com/service' -H 'Origin: https://websocketstest.com' -v
Actual Results:  
$ curl 'wss://websocketstest.com/service' -H 'Origin: https://websocketstest.com' -v
* Protocol "wss" not supported or disabled in libcurl
* Closing connection -1
curl: (1) Protocol "wss" not supported or disabled in libcurl

Expected Results:  
$ curl 'wss://websocketstest.com/service' -H 'Origin: https://websocketstest.com' -v
* processing: wss://websocketstest.com/service
