Description

When this setting is set to 'on', the phone will cache the 'nonce', 'qop', 'opaque' and 'realm' parameters from the initial challenge, as well as the user credentials, and present unbidden an Authorization header (or Proxy-Authorization, depending on the challenge it received) calculated from these cached credentials in the next request it sends on the same identity. The nonce count is incremented on each subsequent message. The server may send a 'nextnonce' in the (Proxy-)Authentication-Info header of the response. The phone will replace the cached nonce with the value of the 'nextnonce' parameter and reset the nonce count. When this setting is set to 'off' the phone will not include any credentials in the next request and must be re-challenged by the server if continued authentication is desired.

Valid Values

'on', 'off'

Default Value

'on'
