The connection infrastructure provides a simple way to make REST-style requests to resources using a variety of protocols.
For the application developer
The Connection API is used to send requests to resources and work with their response. A variety of protocols may be used, including HTTP to work with remote resources and SMTP to send emails.
The destinations addressed by the application using the Connection API may be configured without modification to the application code through the specification of protocol configuration and connection handlers in zero.config.
