http_open_session/2

Availability::- use_module(library(http/http_session)).

Establish a new session. This is normally used if the create option is set to noauto. Options:

renew(+Boolean): If true (default false) and the current request is part of a session, generate a new session-id. By default, this predicate returns the current session as obtained with http_in_session/1.

Errors: permission_error(open, http_session, CGI) if this call is used after closing the CGI header.

- http_close_session/1 for closing the session.
