The authorization scheme to be used when server authorization is to be performed.
Possible ValuesBasic (0)
By default, HTTPAuthScheme is authBasic (0), and if the HTTPUser and HTTPPassword properties are set, the adapter will attempt basic authentication. If HTTPAuthScheme is set to authDigest (1) or authNtlm (4), digest or NTLM authentication will be attempted instead.
If HTTPAuthScheme is set to authProprietary (2) then the authorization token must be supplied through the HTTPAuthorization configuration. Note that, if you set the HTTPAuthorization config, the HTTPAuthScheme will be set automatically to authProprietary (2) by the control.
