Hi Everyone, Upon consideration of your comments, I have decided to adjust my RFC. Please see the updated version https://wiki.php.net/rfc/deprecate-get-post-sessions
Changes include: - session.use_cookies will not be deprecated - session.trans_sid_tags, session.trans_sid_hosts, session.referer_check will get deprecated too (although I am not sure how to implement the deprecation message yet) - the SID constant will also be deprecated as part of this RFC - mentioned that output_add_rewrite_var() will remain unaffected Regards, Kamil
