Note Submitter: core58 at mail dot ru ---- Regarding to "rajneshavon@gmail dot com" note: There only one type of cookies, simply -- cookie is the data storage itself, without any types/categories. Cookies have some parameters (expiration date, domain, path) which should be considered. Sessions mechanism works kinda simply: when You call "session_start();" -- server attaches header Set_cookie: session_name()=session_id(); path=/ usually. This cookie can be used in the next browser request to distinct one user from another (suggesting that session_id() has unique value for every user -- is't usually 32 md-hash). To be completely simple -- server just tries to open file at session storage with the name like sess_<session_id()>. If that file exists -- server reads the data and performs unserialize() and that gives You opportunity to get the stored data as $_SESSION array -- this array is being simply serialized/unserialized when operating with it in scripts. If browser disables cookies -- You can set session.use_trans_sid = 1 That will tell Your PHP parser to append ?session_name()=session_id() to every link being outputted at the page and also add hidden field with that name=value at forms if any. Upon clicking such link with session in the query string, You will receive session_id but from $_GET array. That will tell server where to get session data, just without cookies. The only minus is that Your links will become "variable" with that boring session hash.
