如何用Java代码写get或post请求带cookies类似浏览器按F5刷新效果，
一般情况下，游客用浏览器访问某个网页，后台 会记录此网页被访问次数，当按下浏览器的F5刷新页面后，页面访问次数会增加一次，当再次按下F5刷新，页面访问次数会再次增加一个值，如果做到用HttpConection,HttpGet,这类api在代码中实现请求该页面后，页面访问数量也会增加，请求一次增加一次，多次发送请求就增加多少次，这样，我做了一个，但是这样不行代码如下：
----------------------------------------------
public static void main(String[] args){

doGet("222");
System.out.println("=================>>: 停留1， ");

doGet("222");
System.out.println("=================>>: 停留2， ");

doGet("222");
System.out.println("=================>>: 停留3， ");

doGet("222");
System.out.println("=================>>: 停留4， ");

doGet("222");
System.out.println("=================>>: 停留5， ");

} catch (IOException e) {
e.printStackTrace();
}
}





public static void doGet(String urlStr) throws IOException{
String sessionId = "";
String key = "";
String cookieVal = "";
urlStr = "http://sz.58.com/hezu/29925100345012x.shtml";
URL url = new URL(urlStr);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.connect(); //到此步只是建立与服务器的tcp连接，并未发送http请求
/**
* 设置cookie
*/
if(!sessionId.equals("")){
connection.setRequestProperty("Cookie", sessionId);
}
for(int i=1;(key=connection.getHeaderField(i))!=null;i++){
cookieVal = connection.getHeaderField(i);
cookieVal = cookieVal.substring(0,cookieVal.indexOf(";")>-1?cookieVal.indexOf(";"):cookieVal.length()-1);
sessionId = sessionId + cookieVal + ";";
}

//直到getInputStream()方法调用请求才真正发送出去
BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream()));
StringBuilder sb = new StringBuilder();
String line;
while((line=br.readLine()) != null){
sb.append(line);
sb.append("\n");
}
System.out.println(sb.toString());
br.close();
connection.disconnect();
}
