    //  Cookie Functions - Second Helping  (21-Jan-96)

    //  Written by:  Bill Dortch, hIdaho Design <BDORTCH@NETW.COM>

    //  The following functions are released to the public domain.

    //

    //  The Second Helping version of the cookie functions dispenses with

    //  my encode and decode functions, in favor of JavaScript's new built-in

    //  escape and unescape functions, which do more complete encoding, and

    //  which are probably much faster.

    //

    //  The new version also extends the SetCookie function, though in

    //  a backward-compatible manner, so if you used the First Helping of

    //  cookie functions as they were written, you will not need to change any

    //  code, unless you want to take advantage of the new capabilities.

    //

    //  The following changes were made to SetCookie:

    //

    //  1.  The expires parameter is now optional - that is, you can omit

    //      it instead of passing it null to expire the cookie at the end

    //      of the current session.

    //

    //  2.  An optional path parameter has been added.

    //

    //  3.  An optional domain parameter has been added.

    //

    //  4.  An optional secure parameter has been added.

    //

    //  For information on the significance of these parameters, and

    //  and on cookies in general, please refer to the official cookie

    //  spec, at:

    //

    //      http://www.netscape.com/newsref/std/cookie_spec.html    

    //

    //

    // "Internal" function to return the decoded value of a cookie

    //

    function getCookieVal (offset) {

      var endstr = document.cookie.indexOf (";", offset);

      if (endstr == -1)

        endstr = document.cookie.length;

      return unescape(document.cookie.substring(offset, endstr));

    }



    //

    //  Function to return the value of the cookie specified by "name".

    //    name - String object containing the cookie name.

    //    returns - String object containing the cookie value, or null if

    //      the cookie does not exist.

    //

    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 to create or update a cookie.

    //    name - String object object containing the cookie name.

    //    value - String object containing the cookie value.  May contain

    //      any valid string characters.

    //    [expires] - Date object containing the expiration data of the cookie.  If

    //      omitted or null, expires the cookie at the end of the current session.

    //    [path] - String object indicating the path for which the cookie is valid.

    //      If omitted or null, uses the path of the calling document.

    //    [domain] - String object indicating the domain for which the cookie is

    //      valid.  If omitted or null, uses the domain of the calling document.

    //    [secure] - Boolean (true/false) value indicating whether cookie transmission

    //      requires a secure channel (HTTPS).  

    //

    //  The first two parameters are required.  The others, if supplied, must

    //  be passed in the order listed above.  To omit an unused optional field,

    //  use null as a place holder.  For example, to call SetCookie using name,

    //  value and path, you would code:

    //

    //      SetCookie ("myCookieName", "myCookieValue", null, "/");

    //

    //  Note that trailing omitted parameters do not require a placeholder.

    //

    //  To set a secure cookie for path "/myPath", that expires after the

    //  current session, you might code:

    //

    //      SetCookie (myCookieVar, cookieValueVar, null, "/myPath", null, true);

    //
