为了快速便携地进行操作，您可以查看服务器提供的页面。
To do it quickly and portably, you can check for a page if it's served by the server.
例如你可以：
boolean isAlive = true;
try {
URL hp = new URL("http://yourserver/TestPage.html");
URLConnection hpCon = hp.openConnection();
// add more checks...
} catch (Exception e) {
isAlive = false;
}
这种不太复杂的方法适用于每个http服务器。
This not much sophisticated method will work with every http server.
