-Async Http Client library purpose is to allow Java applications to easily execute HTTP requests and asynchronously process the HTTP responses. The Async HTTP Client library is simple to use. First, in order to add it to your Maven project, simply add this dependency:
-
-        <repository>
-            <id>Sonatype</id>

 Finally, you can also configure the AsyncHttpClient via it's AsyncHttpClientConfig object:

 The library uses Java non blocking I/O for supporting asynchronous operations. The default asynchronous provider is build on top of Netty (http://www.jboss.org/netty), the Java NIO Client Server Socket Framework from JBoss, but the library exposes a configurable provider SPI which allows to easily plug in other frameworks.
