force_disconnection_at_end_of_session()

static void html_disconnect::force_disconnection_at_end_of_session ( bool  val )

inlinestatic

whether to emulate user logout while using basic authentication (see also class server)

Note

in version 1.0 web authentication relies on basic authentication schema, which does not have any mean to provide disconnection. To emulate such disconnection, each new TCP session requires to reauthentification from the user. A web browser may decide to tear down and recreate a new TCP session after some time, which will requirer the user to reauthenticate while from user stand point this is the same web/http session. To avoid this, it is possible to only rely on the basic authnentication and upon new TCP session, the server object only validate that the HTTP header has a valid credentials. The drawback is that deauthentication is not possible unless the browser is restarted. The following call define the either the first (true) ot the second (false) previously described behaviors for all server objects. This is a static method because it is expected to be removed in the future when the session object will keep trace of valid authentication tokens (stored as cookies or basic authentication with volatile temporary password also stored and eventually removed from an internal base the challenge object would have access to.
