Cookies implement on client side

Cookie is a small text file sent by web server and saved by web browser on client machine.

There two type of cookies
Persistent cookies:  cookies are stored on your computer hard disk.  They stay on your hard disk and can be accessed by web servers until they are deleted or have expired.

Non-persistent cookies: cookies are saved only while your web browser is running.  They can be used by a web server only until you close your browser.  They are not saved on your disk.

Implement non-persistent cookie using java script

//Check session cookie
function bswayedcheckSessionCookie() {

    var date = new Date();
    var todayDate = date.getTime();

    var cookieName = GetSessionCookie();

    if (cookieName == "") {
        var cookieName = "bSwayedSession" + todayDate;
        cookieName = SetSessionCookie(cookieName);
    }
    return cookieName;
}


//Read session cookies
function GetSessionCookie() {

    var name = "bSwayedSession";

    var cookieArray = document.cookie.split(/[\;=\s]/);

    for (var i = 0; i < cookieArray.length; i++) {
        var cookieName = $jq191.trim(cookieArray[i]);  

        if (cookieName.indexOf(name) == 0) {
            return cookieName;
        }
    }
    return "";
}

//Set cookie
function SetSessionCookie(sessionCookieName) {
    document.cookie = "BswayedSession" + "=" + sessionCookieName;
    return document.cookie;
}
