HttpClient provides an efficient, asynchronous, non-blocking implementation to perform HTTP requests to a server through a simple API that offers also blocking semantic.

HttpClient provides easy-to-use methods such as GET(String) that allow to perform HTTP requests in a one-liner, but also gives the ability to fine tune the configuration of requests via newRequest(URI).

HttpClient acts as a central configuration point for network parameters (such as idle timeouts) and HTTP parameters (such as whether to follow redirects).

HttpClient transparently pools connections to servers, but allows direct control of connections for cases where this is needed.

HttpClient also acts as a central configuration point for cookies, via getHttpCookieStore().

Typical usage:


 HttpClient httpClient = new HttpClient();
 httpClient.start();

 // One liner:
 httpClient.GET("http://localhost:8080/").getStatus();

 // Building a request with a timeout
 ContentResponse response = httpClient.newRequest("http://localhost:8080")
         .timeout(5, TimeUnit.SECONDS)
         .send();
 int status = response.status();

 // Asynchronously
 httpClient.newRequest("http://localhost:8080").send(result ->
 {
     Response response = result.getResponse();
     ...
 });
