PoolingHttpClientConnectionManager.@Deprecated @Contract(threading=SAFE_CONDITIONAL) public class PoolingClientConnectionManager extends Object implements ClientConnectionManager, org.apache.http.pool.ConnPoolControl<HttpRoute>
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.
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.
