//
// 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
// 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);
//
