Authenticated Resources

For resources requiring authentication (like private repos), Credential can be configured for it. So far, only AuthorizationHeader is implemented.

Credentials will only be used when the configured url pattern matches the outbound request. Examples can be found in puml-demo.yaml

Proxy Authentication

If proxy authentication is required, it auto retries the request using http(s).proxyUser and http(s).proxyPassword system property.
