@Deprecated @Contract(threading=SAFE_CONDITIONAL) public class PoolingClientConnectionManager extends java.lang.Object implements ClientConnectionManager, org.apache.http.pool.ConnPoolControl<HttpRoute>
Deprecated.(4.3) usePoolingHttpClientConnectionManager
.Manages a pool ofOperatedClientConnection
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.

releaseConnection
public void releaseConnection(ManagedClientConnection conn, long keepalive, java.util.concurrent.TimeUnit timeUnit)
Deprecated.Description copied from interface:ClientConnectionManager
Releases a connection for use by others. You may optionally specify how long the connection is valid to be reused. Values <= 0 are considered to be valid forever. If the connection is not marked as reusable, the connection will not be reused regardless of the valid duration. If the connection has been released before, the call will be ignored.- Specified by:
releaseConnection
in interfaceClientConnectionManager
- Parameters:
conn
- the connection to releasekeepalive
- the duration of time this connection is valid for reusetimeUnit
- the unit of time validDuration is measured in- See Also:
ClientConnectionManager.closeExpiredConnections()
-
