Dear Mayo,

The HTTP Advanced sensors supports three types of authentication:

  • Basic access authentication (HTTP) : Use simple HTTP authentication. This is the default setting and suitable for most cases. Note: This authentication method transmits credentials as plain text.
  • Windows NT LAN Manager (NTLM) : Use the Microsoft NTLM protocol for authentication. This is sometimes used in intranets for single sign-on.
  • Digest Access Authentication: Use digest access authentication that applies a hash function to the password which is safer than basic access authentication.

If the website required another authentication method, you might want to use the POST method to authenticate, or create a custom script.

Best regards, Felix
