in Express 3 you can do it as:
req.header("custom-header")
req.get("custom-header")
and also since express request is a node IncomingMessage you can use:
req.headers["custom-header"]
Please check the "*subtle"* differences,
- all three examples uses "REQUEST" not response as in one of your
examples.
- the first two examples are functions but the last on is an object
hope this help.
