Package org.apache.http.client Description
</H2>

<P>
The API for client-side HTTP communication and
entry point to the <i>HttpClient</i> module.
<p/>
The usual execution flow can be demonstrated by the 
code snippet below:

<PRE>
HttpClient httpclient = new DefaultHttpClient();

// Prepare a request object
HttpGet httpget = new HttpGet("http://www.apache.org/"); 

// Execute the request
HttpResponse response = httpclient.execute(httpget);

// Examine the response status
System.out.println(response.getStatusLine());

// Get hold of the response entity
HttpEntity entity = response.getEntity();

// If the response does not enclose an entity, there is no need
// to worry about connection release
if (entity != null) {
    InputStream instream = entity.getContent();
    try {
        
        BufferedReader reader = new BufferedReader(
                new InputStreamReader(instream));
        // do something useful with the response
        System.out.println(reader.readLine());
        
    } catch (IOException ex) {

        // In case of an IOException the connection will be released
        // back to the connection manager automatically
        throw ex;
        
    } catch (RuntimeException ex) {

        // In case of an unexpected exception you may want to abort
        // the HTTP request in order to shut down the underlying 
        // connection and release it back to the connection manager.
        httpget.abort();
        throw ex;
        
    } finally {

        // Closing the input stream will trigger connection release
        instream.close();
        
    }
}
