/**
 * Default implementation of {@link org.apache.http.client.HttpClient} pre-configured
 * for most common use scenarios.
 * 

* Please see the Javadoc for {@link #createHttpProcessor()} for the details of the interceptors * that are set up by default. *

* Additional interceptors can be added as follows, but * take care not to add the same interceptor more than once. *

 * DefaultHttpClient httpclient = new DefaultHttpClient();
 * httpclient.addRequestInterceptor(new RequestAcceptEncoding());
 * httpclient.addResponseInterceptor(new ResponseContentEncoding());
 * 
*

  • NoTcpDelay: true
  • *
  • SocketBufferSize: 8192
