This class provides a concrete implementation of CookieHandler. It separates the storage of cookies from the policy which decides to accept or deny cookies. The constructor can have two arguments: a CookieStore and a CookiePolicy. The former is in charge of cookie storage and the latter makes decision on acceptance/rejection. CookieHandler is in the center of cookie management. User can make use of CookieHandler.setDefault to set a CookieManager as the default one used. CookieManager.put uses CookiePolicy.shouldAccept to decide whether to put some cookies into a cookie store. Three built-in CookiePolicy is defined: ACCEPT_ALL, ACCEPT_NONE and ACCEPT_ORIGINAL_SERVER. Users can also customize the policy by implementing CookiePolicy. Any accepted HTTP cookie is stored in CookieStore and users can also have their own implementation. Up to now, Only add(URI, HttpCookie) and get(URI) are used by CookieManager. Other methods in this class may probably be used in a more complicated implementation. There are many ways to customize user's own HTTP cookie management: First, call CookieHandler.setDefault to set a new CookieHandler implementation. Second, call CookieHandler.getDefault to use CookieManager. The CookiePolicy and CookieStore used are customized. Third, use the customized CookiePolicy and the CookieStore. This implementation conforms to RFC 2965 section 3.3.
