Namespace: System.Net
Assembly: System (in System.dll)
| Member name | Description | |
|---|---|---|
.png?cs-save-lang=1&cs-lang=cpp "Supported in .NET for Windows Store apps") | None | No authentication is allowed. A client requesting an HttpListener object with this flag set will always receive a 403 Forbidden status. Use this flag when a resource should never be served to a client. |
| Digest | Specifies digest authentication. For additional information, see RFC2617 – HTTP Authentication: Basic and Digest Authentication. This document is available at http://www.rfc-editor.org |
| Negotiate | Negotiates with the client to determine the authentication scheme. If both client and server support Kerberos, it is used; otherwise, NTLM is used. |
| Ntlm | Specifies NTLM authentication. |
| Basic | Specifies basic authentication. For additional information, see RFC2617 – HTTP Authentication: Basic and Digest Authentication. This document is available at http://www.rfc-editor.org. |
| Anonymous | Specifies anonymous authentication. |
| IntegratedWindowsAuthentication | Specifies Windows authentication. |
This enumeration is used to specify the method used to authenticate client requests being processed by HttpListener objects.
Note Basic authentication requires the exchange of a password and should therefore be avoided except in the case of secure, encrypted connections.
