	// Envoy Headers
	'x-ot-span-context',
	'x-request-id',

	// Zipkin Headers

Whats new?

1.0.3

Breaking changes, unicity-forward-headers now expects the headers object directly and not request or response objects. Also made it lowercase incoming headers to ensure dupliates are handled correctly.

Example

const ForwardHeaders = require('unicity-forward-headers');

response.headers = ForwardHeaders(request.headers, response.headers);

const ForwardHeaders = require('unicity-forward-headers');

response.headers = ForwardHeaders(request.headers);
