In this article, I would like to demonstrate page visiting counter using cookies.

These are the steps for implementing the same
  1. Create one aspx file in visual studio 2005/200/2010

  2. Copy the script shown below in between script tag

    <script language="JavaScript" type="text/javascript">
     function GetCookie(name) {
    var arg = name + "=";
    var alen = arg.length;
    var clen = document.cookie.length;
    var i = 0;
    while (i < clen) {
    var j = i + alen;
    if (document.cookie.substring(i, j) == arg)
    return getCookieVal(j);
    i = document.cookie.indexOf(" ", i) + 1;
    if (i == 0) break;
    }
    return null;
    }
    function SetCookie(name, value) {
    var argv = SetCookie.arguments;
    var argc = SetCookie.arguments.length;
    var expires = (argc > 2) ? argv[2] : null;
    var path = (argc > 3) ? argv[3] : null;
    var domain = (argc > 4) ? argv[4] : null;
    var secure = (argc > 5) ? argv[5] : false;
    document.cookie = name + "=" + escape(value) +
    ((expires == null) ? "" : ("; expires=" + expires.toGMTString())) +
    ((path == null) ? "" : ("; path=" + path)) +
    ((domain == null) ? "" : ("; domain=" + domain)) +
    ((secure == true) ? "; secure" : "");
    }
    function DeleteCookie(name) {
    var exp = new Date();
    exp.setTime(exp.getTime() - 1);
    var cval = GetCookie(name);
    document.cookie = name + "=" + cval + "; expires=" + exp.toGMTString();
    }
    var expDays = 30;
    var exp = new Date();
    exp.setTime(exp.getTime() + (expDays * 24 * 60 * 60 * 1000));
    function amt() {
    var count = GetCookie('count')
    if (count == null) {
    SetCookie('count', '1')
    return 1
    }
    else {
    var newcount = parseInt(count) + 1;
    DeleteCookie('count')
    SetCookie('count', newcount, exp)
    return count
    }
    }
    function getCookieVal(offset) {
    var endstr = document.cookie.indexOf(";", offset);
    if (endstr == -1)
    endstr = document.cookie.length;
    return unescape(document.cookie.substring(offset, endstr));
    }
     </script>

  3. Paste this code in between <body> tag

    <body>
     <form id="form1" runat="server">
     <script language="JavaScript">
     document.write("You've been here <b>" + amt() + "</b> times.")
     </script>
     </form>
    </body>

Finally run the application to view the page count. If you refresh the page, the counter will increment by one.
