Determines type of authentication with the web server.

A HttpAuthentications enumeration.  

object.Authentication [= value]

The Authentication Property syntax has these parts:

The settings for value are:

Constant		Value	Description
	AuthNone	0	No authentication
	AuthAutomatic	1	Auto select authentication
	AuthBasic	2	Basic authentication
	AuthNTLM	3	NTLM authentication
	AuthDigest	4	Digest authentication
	AuthWindowsIntegrated	5	Windows Integrated authentication

Authentication property determines if wodHttpDLX should authenticate with the web server to access protected resource. In most cases this is not needed, but sometimes access to restricted areas may be needed.

For this purpose, wodHttpDLX can authenticate using Basic and NTLM authentication. NTLM is far more secure, because password is *never* sent over insecure network to the remote side. Rather, sequence of challenge/response messages are sent during this authentication. wodHttpDLX has been tested with MS Proxy and IIS server for NTLM authentication. Basic authentication (using base64 encoded login and password) if far more widespread, and is used by many proxy and WEB servers.

If you don't want to authenticate with the server, you can either set Authentication to AuthNone value, or you can leave login/password properties empty.

If you specify authentication mode explicitly, using AuthBasic or AuthNTLM value, wodHttpDLX will immediately in your next request send authentication request to the server.

The best option (and default, of course) is AuthAutomatic value, which will try to access the resource without any login/password information, and then resend requests WITH authentication information only if server returned 'access denied' response. In this case, wodHttpDLX can issue many requests in order to pass through proxy and WEB server protections. Make sure that AutoRedirect property is set to True (it is by default) in such cases. After all those requests are internally sent, Done event will be fired only once - when wodHttpDLX has completed it's job, either successfully or with error response from the remote side

Don't forget that AuthNTLM may use MyHostname property to identify your computer to the server! You may want to clear it out if you're accessing HTTP server outside your domain!

When AuthWindowsIntegrated is selected, wodHttpDLX will send login and password of currently logged in Windows user. This type of authentication is used with NTLM authentication type.
