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.
