// START Basic Cookie Scripts Created 14 Sept 2008

// Function 1: setCookie(name,value,days)
// Function 2: getCookie(name)				// returns the cookie value
// Function 3: clearCookie(name)

// Note: To make things clear, cookie names begin with "c_"

//The following functions contains parts that derives from the Cookies tutorial on quirksmode.org
function setCookie(name,value,days){

	if (days){

		var date=new Date();
		// the math behind setting the date
		date.setTime(date.getTime()+(days*24*60*60*1000));
		// get a new var to hold the date in GMT format
		var expires=date.toGMTString();
		} else {

		var expires="";
