I would like to use the Session Initiated Protocol [source](https://blog.wildix.com/subscribe-notify-methods/) with standard Node-RED http nodes.
> A user agent interested in event notification sends a SUBSCRIBE message to an SIP server. The SUBSCRIBE message establishes a dialog and is immediately followed by the server replying with 200 OK response. At this point the dialog is established. The server sends a NOTIFY request to the user every time the event to which the user subscribed changes. NOTIFY messages are sent within the dialog established by the SUBSCRIBE.
[More information](https://tools.ietf.org/html/rfc3261)
For that I need 2 things:
1. http - in node: Supporting method "NOTIFY"
2. http - request node: Supporting "SUBSCRIBE" / "UNSUBSCRIBE"
Topic 2. does already work when using `- set by msg.method - ` in spite of documentation saying that only the value put, get, etc are allowed.
