org.asynchttpclient.AsyncHttpClient

ing.com/").execute(); The code above will block until the response is fully received. To execute asynchronous HTTP request, you create an {@link AsyncHandler} or its abstract implementation, {@link AsyncCompletionHandler}

 AsyncHttpClient c = new AsyncHttpClient(); Future f = c.prepareGet("http://www.ning.com/").execute(new AsyncCompletionHandler() {  @Override public Response onCompleted(Response response) throws IOException { // Do something return response; } 
 @Override public void onThrowable(Throwable t) { } }); Response response = f.get(); 
 // We are just interested to retrieve the status code. Future f = c.prepareGet("http://www.ning.com/").execute(new AsyncCompletionHandler() { 
 @Override public Integer onCompleted(Response response) throws IOException { // Do something return response.getStatusCode(); } 
 @Override public void onThrowable(Throwable t) { } }); Integer statusCode = f.get();

You can also have more control about the how the response is asynchronously processed by using a {@link AsyncHandler}

 AsyncHttpClient c = new AsyncHttpClient(); Future f = c.prepareGet("http://www.ning.com/").execute(new AsyncHandler() { private StringBuilder builder = new StringBuilder();  @Override public STATE onStatusReceived(HttpResponseStatus s) throws Exception { // return STATE.CONTINUE or STATE.ABORT return STATE.CONTINUE } 
 @Override public STATE onHeadersReceived(HttpResponseHeaders bodyPart) throws Exception { // return STATE.CONTINUE or STATE.ABORT return STATE.CONTINUE 
 } @Override 
 public STATE onBodyPartReceived(HttpResponseBodyPart bodyPart) throws Exception { builder.append(new String(bodyPart)); // return STATE.CONTINUE or STATE.ABORT return STATE.CONTINUE } 
 @Override public String onCompleted() throws Exception { // Will be invoked once the response has been fully read or a ResponseComplete exception // has been thrown. return builder.toString(); } 
 @Override public void onThrowable(Throwable t) { } }); 
 String bodyResponse = f.get();

This class can also be used without the need of {@link AsyncHandler}

 AsyncHttpClient c = new AsyncHttpClient(); Future f = c.prepareGet(TARGET_URL).execute(); Response r = f.get();

Finally, you can configure the AsyncHttpClient using an {@link AsyncHttpClientConfig} instance

 AsyncHttpClient c = new AsyncHttpClient(new AsyncHttpClientConfig.Builder().setRequestTimeoutInMs(...).build()); Future f = c.prepareGet(TARGET_URL).execute(); Response r = f.get();

An instance of this class will cache every HTTP 1.1 connections and close them when the {@link AsyncHttpClientConfig#getReadTimeout()}expires. This object can hold many persistent connections to different host.
