-/**
- * NTLMAuthentication:
- *
- * @author Michael McMahon
- */
-
-/*
- * NTLM authentication is nominally based on the framework defined in RFC2617,
- * but differs from the standard (Basic & Digest) schemes as follows:
- *
- * 1. A complete authentication requires three request/response transactions
- * as shown below:
- * REQ ------------------------------->
- * <---- 401 (signalling NTLM) --------
- *
- * REQ (with type1 NTLM msg) --------->
- * <---- 401 (with type 2 NTLM msg) ---
- *
- * REQ (with type3 NTLM msg) --------->
- * <---- OK ---------------------------
- *
- * 2. The scope of the authentication is the TCP connection (which must be kept-alive)
- * after the type2 response is received. This means that NTLM does not work end-to-end
- * through a proxy, rather between client and proxy, or between client and server (with no proxy)
