	/*

	The session works the following way:

	1. When a visitor loads a page from the site the script checks if cookies_on varibale has been passed to it as a cookie.
	2. If it has been passed, the script tries to get Session ID (SID) from the request:
	3. Depending on session mode the script is getting SID differently.
	The following modes are available:

	smAUTO - Automatic mode: if cookies are on at the client side, the script relays only on cookies and
	ignore all other methods of passing SID.
	If cookies are off at the client side, the script relays on SID passed through query string
	and referal passed by the client. THIS METHOD IS NOT 100% SECURE, as long as attacker may
	get SID and substitude referal to gain access to user' session. One of the faults of this method
	is that the session is only created when the visitor clicks the first link on the site, so
	there is NO session at the first load of the page. (Actually there is a session, but it gets lost
	after the first click because we do not use SID in query string while we are not sure if we need it)

	smCOOKIES_ONLY - Cookies only: in this mode the script relays solely on cookies passed from the browser
	and ignores all other methods. In this mode there is no way to use sessions for clients
	without cookies support or cookies support disabled. The cookies are stored with the
	full domain name and path to base-directory of script installation.

	smGET_ONLY - GET only: the script will not set any cookies and will use only SID passed in
	query string using GET, it will also check referal. The script will set SID at the
	first load of the page

	smCOOKIES_AND_GET - Combined mode: the script will use both cookies and GET right from the start. If client has
	cookies enabled, the script will check SID stored in cookie and passed in query string, and will
	use this SID only if both cookie and query string matches. However if cookies are disabled on the
	client side, the script will work the same way as in GET_ONLY mode.

	-4. After the script has the SID it tries to laod it from the Storage (default is database)
	+4. After the script has the SID it tries to load it from the Storage (default is database)
	5. If such SID is found in the database, the script checks its expiration time. If session is not expired, it updates
	its expiration, and resend the cookie (if applicable to session mode)
	6. Then the script loads all the data (session variables) pertaining to the SID.



	Usage:

	$session =& new Session(smAUTO); //smAUTO is default, you could just leave the brackets empty, or provide another mode

	$session->SetCookieDomain('my.domain.com');
	$session->SetCookiePath('/myscript');
	$session->SetCookieName('my_sid_cookie');
	$session->SetGETName('sid');
	$session->InitSession();

	...

	//link output:

	echo "<a href='index.php?'". ( $session->NeedQueryString() ? 'sid='.$session->SID : '' ) .">My Link</a>";
