From source file:com.hilatest.httpclient.apacheexample.ClientAbortMethod.java

public final static void main(String[] args) throws Exception {
    HttpClient httpclient = new DefaultHttpClient();

    HttpGet httpget = new HttpGet("http://www.apache.org/");

    System.out.println("executing request " + httpget.getURI());

    HttpEntity entity = response.getEntity();

    System.out.println("----------------------------------------");
    System.out.println(response.getStatusLine());
    if (entity != null) {
        System.out.println("Response content length: " + entity.getContentLength());
    }//from  w w  w.j  ava 2  s  . c  om
    System.out.println("----------------------------------------");

    // Do not feel like reading the response body
    // Call abort on the request object
    httpget.abort();

    // When HttpClient instance is no longer needed, 
    // shut down the connection manager to ensure
    // immediate deallocation of all system resources
    httpclient.getConnectionManager().shutdown();
