      //  Cookie Functions -- "Night of the Living Cookie" Version (25-Jul-96)
      //
      //  Written by:  Bill Dortch, hIdaho Design <bdortch@hidaho.com>
      //  The following functions are released to the public domain.
      //
      //  This version takes a more aggressive approach to deleting
      //  cookies.  Previous versions set the expiration date to one
      //  millisecond prior to the current time; however, this method
      //  did not work in Netscape 2.02 (though it does in earlier and
      //  later versions), resulting in "zombie" cookies that would not
      //  die.  DeleteCookie now sets the expiration date to the earliest
      //  usable date (one second into 1970), and sets the cookie's value
      //  to null for good measure.
      //
      //  Also, this version adds optional path and domain parameters to
      //  the DeleteCookie function.  If you specify a path and/or domain
      //  when creating (setting) a cookie**, you must specify the same
      //  path/domain when deleting it, or deletion will not occur.
      //
      //  The FixCookieDate function must now be called explicitly to
      //  correct for the 2.x Mac date bug.  This function should be
      //  called *once* after a Date object is created and before it
      //  is passed (as an expiration date) to SetCookie.  Because the
      //  Mac date bug affects all dates, not just those passed to
      //  SetCookie, you might want to make it a habit to call
      //  FixCookieDate any time you create a new Date object:
      //
      //    var theDate = new Date();
      //    FixCookieDate (theDate);
      //
      //  Calling FixCookieDate has no effect on platforms other than
      //  the Mac, so there is no need to determine the user's platform
      //  prior to calling it.
      //
      //  This version also incorporates several minor coding improvements.
      //
      //  **Note that it is possible to set multiple cookies with the same
      //  name but different (nested) paths.  For example:
      //
      //    SetCookie ("color","red",null,"/outer");
      //    SetCookie ("color","blue",null,"/outer/inner");
      //
      //  However, GetCookie cannot distinguish between these and will return
      //  the first cookie that matches a given name.  It is therefore
      //  recommended that you *not* use the same name for cookies with
      //  different paths.  (Bear in mind that there is *always* a path
      //  associated with a cookie; if you don't explicitly specify one,
      //  the path of the setting document is used.)
      //  
      //  Revision History:
      //
      //    "Toss Your Cookies" Version (22-Mar-96)
      //      - Added FixCookieDate() function to correct for Mac date bug
      //
      //    "Second Helping" Version (21-Jan-96)
      //      - Added path, domain and secure parameters to SetCookie
      //      - Replaced home-rolled encode/decode functions with Netscape's
      //        new (then) escape and unescape functions
      //
      //    "Free Cookies" Version (December 95)
      //

      //  Function to create or update a cookie.
      //    name - String 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

      //
      //  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:
