*
* - {@link HttpRequestExecutor} object used to transmit messages
* over HTTP connections. The {@link #createRequestExecutor()} must be
* implemented by concrete super classes to instantiate this object.
*
* - {@link BasicHttpProcessor} object to manage a list of protocol
* interceptors and apply cross-cutting protocol logic to all incoming
* and outgoing HTTP messages. The {@link #createHttpProcessor()} must be
* implemented by concrete super classes to instantiate this object.
*
* - {@link HttpRequestRetryHandler} object used to decide whether
* or not a failed HTTP request is safe to retry automatically.
* The {@link #createHttpRequestRetryHandler()} must be
* implemented by concrete super classes to instantiate this object.
*
* - {@link ClientConnectionManager} object used to manage
* persistent HTTP connections.
*
* - {@link ConnectionReuseStrategy} object used to decide whether
* or not a HTTP connection can be kept alive and re-used for subsequent
* HTTP requests. The {@link #createConnectionReuseStrategy()} must be
* implemented by concrete super classes to instantiate this object.
*
* - {@link ConnectionKeepAliveStrategy} object used to decide how
* long a persistent HTTP connection can be kept alive.
* The {@link #createConnectionKeepAliveStrategy()} must be
* implemented by concrete super classes to instantiate this object.
*
* - {@link CookieSpecRegistry} object used to maintain a list of
* supported cookie specifications.
* The {@link #createCookieSpecRegistry()} must be implemented by concrete
* super classes to instantiate this object.
*
* - {@link CookieStore} object used to maintain a collection of
* cookies. The {@link #createCookieStore()} must be implemented by
* concrete super classes to instantiate this object.
*
* - {@link AuthSchemeRegistry} object used to maintain a list of
* supported authentication schemes.
* The {@link #createAuthSchemeRegistry()} must be implemented by concrete
* super classes to instantiate this object.
*
* - {@link CredentialsProvider} object used to maintain
* a collection user credentials. The {@link #createCredentialsProvider()}
* must be implemented by concrete super classes to instantiate
* this object.
*
* - {@link AuthenticationStrategy} object used to authenticate
* against the target host.
* The {@link #createTargetAuthenticationStrategy()} must be implemented
* by concrete super classes to instantiate this object.
*
* - {@link AuthenticationStrategy} object used to authenticate
* against the proxy host.
* The {@link #createProxyAuthenticationStrategy()} must be implemented
* by concrete super classes to instantiate this object.
*
* - {@link HttpRoutePlanner} object used to calculate a route
* for establishing a connection to the target host. The route
* may involve multiple intermediate hops.
* The {@link #createHttpRoutePlanner()} must be implemented
* by concrete super classes to instantiate this object.
*
* - {@link RedirectStrategy} object used to determine if an HTTP
* request should be redirected to a new location in response to an HTTP
* response received from the target server.
*
* - {@link UserTokenHandler} object used to determine if the
* execution context is user identity specific.
* The {@link #createUserTokenHandler()} must be implemented by
* concrete super classes to instantiate this object.
*
*
*
* This class also maintains a list of protocol interceptors intended
* for processing outgoing requests and incoming responses and provides
* methods for managing those interceptors. New protocol interceptors can be
* introduced to the protocol processor chain or removed from it if needed.
* Internally protocol interceptors are stored in a simple
* {@link java.util.ArrayList}. They are executed in the same natural order
* as they are added to the list.
*
* AbstractHttpClient is thread safe. It is recommended that the same
* instance of this class is reused for multiple request executions.
* When an instance of DefaultHttpClient is no longer needed and is about
* to go out of scope the connection manager associated with it must be
* shut down by calling {@link ClientConnectionManager#shutdown()}!
*
* @since 4.0
*
* @deprecated (4.3) use {@link HttpClientBuilder}.
