+/**
+ * Manages a pool of {@link ch.boye.httpclientandroidlib.conn.OperatedClientConnection}
+ * and is able to service connection requests from multiple execution threads.
+ * Connections are pooled on a per route basis. A request for a route which
+ * already the manager has persistent connections for available in the pool
+ * will be services by leasing a connection from the pool rather than
+ * creating a brand new connection.
+ * <p>
+ * PoolingConnectionManager maintains a maximum limit of connection on
+ * a per route basis and in total. Per default this implementation will
+ * create no more than than 2 concurrent connections per given route
+ * and no more 20 connections in total. For many real-world applications
+ * these limits may prove too constraining, especially if they use HTTP
+ * as a transport protocol for their services. Connection limits, however,
+ * can be adjusted using HTTP parameters.
+ *
+ * @since 4.2
+ *
+ * @deprecated (4.3) use {@link PoolingHttpClientConnectionManager}.
