Content-Length: 0 There is also an older way to configure the settings directly in the settings file. For implementations wishing to work with M$'s software this means that they must make sure they use either HTTP/1.0 keep-alive's or HTTP/1.1 persistent connections, and that they must be prepared to do the second part of the handshake each time the connection was closed and is reopened. When the browser received the redirect authentication request, it will check the source of the requirement.

Time: The 8-byte little-endian time in GMT. RFC 7486 3 HTTP (HTTP Origin-Bound Authentication). It is an array of 8 arbitrary bytes. If customer selected the second option, "Automatic logon only in Intranet zone": If customer selected the third option, "Automatic logon with current user name and password": If customer selected the fourth option, "Prompt for user name and password", the browser will always pop up the input window until pass. The 12th annual .NET Conference is the virtual place to be for forward thinking developers who are looking to learn, celebrate, and collaborate. security,webauthn. Value: one of the values below: If a client/server program uses the NTLM SSP (or uses secure Remote Procedure Call [RPC], which uses the NTLM SSP) to provide session security for a connection, the type of session security to use is determined as follows: You can use the NtlmMinClientSec value to cause client/server connections to either negotiate a given quality of session security or not to succeed.
