public class HelloHttpClientMain {
public static void main(String[] args) {
String url = "http://localhost:8080/myweb/hello.html";
HttpClient client = new HttpClient();
HttpMethod method = new GetMethod(url);
method.addRequestHeader("Connection", "close");
try {
client.executeMethod(method);
byte[] responseBody = method.getResponseBody();
System.out.println(new String(responseBody));
} catch (HttpException e) {
