| * CookieParser is an interface to a utility to to get and set values |
| * of Cookies on the Client Browser. You can use CookieParser to convert |
| * Cookie values to various types or to set Bean values with setParameters(). |
| * Servlet Spec for more information on Cookies. |
| * <p> |
| * Use set() or unset() to Create or Destroy Cookies. |
| * <p> |
| * NOTE: The name= portion of a name=value pair may be converted |
| * to lowercase or uppercase when the object is initialized and when |
| * new data is added. This behaviour is determined by the url.case.folding |
| * property in TurbineResources.properties. Adding a name/value pair may |
| * overwrite existing name=value pairs if the names match: |
| * |
| * <pre> |
| * CookieParser cp = data.getCookies(); |
| * cp.add("ERROR",1); |
| * cp.add("eRrOr",2); |
| * int result = cp.getInt("ERROR"); |
| * </pre> |
| * |
| * In the above example, result is 2. |
