Use cookies. google it with javascript and cookies. There are a ton of functions for it.

There are more ways to do it than just cookies - it basicaly depends if you want to store the session between visits that happend at the same time, or if you want to save sessions for later use.

If the later is what you want, go for cookies:

function createCookie(name,value,days) {

    if (days) {

        var date = new Date();

        date.setTime(date.getTime()+(days*24*60*60*1000));

        var expires = "; expires="+date.toGMTString();

    }

    else var expires = "";

    document.cookie = name+"="+value+expires+"; path=/";

}





function readCookie(name) {

    var nameEQ = name + "=";

    var ca = document.cookie.split(';');

    for(var i=0;i < ca.length;i++) {

        var c = ca[i];

        while (c.charAt(0)==' ') c = c.substring(1,c.length);

        if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);

    }

    return null;

}



function eraseCookie(name) {

    createCookie(name,"",-1);

}

 

If you just want to save the session while the user leaves your pages you could use a hidden frame and store the session value inside a hidden input.
