A CookieManager is initialized with a {@link CookieStore} * which manages storage, and a {@link CookiePolicy} object, which makes * policy decisions on cookie acceptance/rejection. * * <p> The HTTP cookie management in java.net package looks like: * <blockquote> * <pre>{@code * use * CookieHandler <------- HttpURLConnection * ^ * | impl * | use * CookieManager -------> CookiePolicy * | use * |--------> HttpCookie * | ^ * | | use * | use | * |--------> CookieStore * ^ * | impl * | * Internal in-memory implementation * }</pre> * <ul> * <li> * CookieHandler is at the core of cookie management. User can call * CookieHandler.setDefault to set a concrete CookieHandler implementation * to be used. * </li> * <li> * CookiePolicy.shouldAccept will be called by CookieManager.put to see whether * or not one cookie should be accepted and put into cookie store. User can use * any of three pre-defined CookiePolicy, namely ACCEPT_ALL, ACCEPT_NONE and * ACCEPT_ORIGINAL_SERVER, or user can define his own CookiePolicy implementation * and tell CookieManager to use it. * </li> * <li> * CookieStore is the place where any accepted HTTP cookie is stored in. * If not specified when created, a CookieManager instance will use an internal * in-memory implementation. Or user can implements one and tell CookieManager * to use it. * </li> * <li> * Currently, only CookieStore.add(URI, HttpCookie) and CookieStore.get(URI) * are used by CookieManager. Others are for completeness and might be needed * by a more sophisticated CookieStore implementation, e.g. a NetscapeCookieStore. * </li> * </ul> * </blockquote> * * <p>There're various ways user can hook up his own HTTP cookie management behavior, e.g. * <blockquote> * <ul> * <li>Use CookieHandler.setDefault to set a brand new {@link CookieHandler} implementation * <li>Let CookieManager be the default {@link CookieHandler} implementation, * but implement user's own {@link CookieStore} and {@link CookiePolicy} * and tell default CookieManager to use them: * <blockquote><pre> * // this should be done at the beginning of an HTTP session * CookieHandler.setDefault(new CookieManager(new MyCookieStore(), new MyCookiePolicy())); * </pre></blockquote> * <li>Let CookieManager be the default {@link CookieHandler} implementation, but * use customized {@link CookiePolicy}: * <blockquote><pre> * // this should be done at the beginning of an HTTP session * CookieHandler.setDefault(new CookieManager()); * // this can be done at any point of an HTTP session * ((CookieManager)CookieHandler.getDefault()).setCookiePolicy(new MyCookiePolicy()); * </pre></blockquote> * </ul> * </blockquote> * * <p>The implementation conforms to <a href="http://www.ietf.org/rfc/rfc2965.txt">RFC 2965</a>, section 3.3. * * @see CookiePolicy * @author Edward Wang * @since 1.6 */ public class CookieManager extends CookieHandler { /* ---------------- Fields -------------- */ private CookiePolicy policyCallback; private CookieStore cookieJar = null; /* ---------------- Ctors -------------- */ /** * Create a new cookie manager. * * <p>This constructor will create new cookie manager with default * cookie store and accept policy.
