What is HTTP Authentication ?
HTTP provides a general framework for access control and authentication. The most common HTTP authentication scheme is the "Basic" authentication. Whenever an HTTP Basic Authentication filter is configured, the Enterprise Gateway requests the client to present a username and password combination as part of the HTTP Basic challenge-response mechanism. With HTTP Basic Authentication, the client's username and password are concatenated, base64-encoded, and passed in the Authorization HTTP header as follows:
