I'm working with Twilio webhooks for Programmable Voice, writing some simple TwiML responses in a Go API.
Reviewing the Webhook Connection Overrides doc, I see a general link to https://en.wikipedia.org/wiki/URL. Are URL extensions
a standard HTTP scheme defined within an RFC, or is this a Twilio-specific convention using the Same Document Reference
as stated in https://www.rfc-editor.org/rfc/rfc3986#section-4.4 ?
I'm asking this to properly use net/http
in Go.
