Class DefaultHttpClientProvider

java.lang.Object

com.atlassian.crowd.integration.rest.service.DefaultHttpClientProvider

All Implemented Interfaces:

HttpClientProvider

public class DefaultHttpClientProvider
extends Object
implements HttpClientProvider

Default implementation of HttpClientProvider that creates http clients with client-side caching support.

This implementation uses a PoolingHttpClientConnectionManager, which pools connections on a per-route basis, and is able to service connection requests from multiple execution threads. Clients should call Closeable.close() to cleanup resources held by the connection manager.
