发送/接收http报头的问题

[zidanejava]

请问一个发送/接收http报头的问题:

如:我要发送如下信息:

POST /nav/getsystemconfig.aspx HTTP/1.1
User-Agent: IIC2.0/PC 2.2.0230
Content-Type: application/x-www-form-urlencode; charset=utf-8
Host: nav.fetion.com.cn
Content-Length: 75
Connection: Keep-Alive

从而得到如下信息:

HTTP/1.1 200 OK
DATE: Wed, 11 Apr 2007 08:19:39 GMT
Server: Microsoft-IIS/6.0
X-Powered-By: ASP.NET
X-AspNet-Version: 2.0.50727
Content-Language: zh-cn
Set-Cookie: ASP.NET_SessionId=3siqq555hhsjllshshsssw32; path=/; HttpOnly
Cache-Control: private
Content-Type: text/html; charset=utf-8
Content-Length: 202

<?xml version="1.0" encoding="utf-8" ?><config><client version="2.0.0.0"><compatible>
2.0.0.0</compatible><date>2006-7-27 18:48:27</date><pc-live-update value="http://221.130.45.198"/></client></config>

怎么实现的!急......最好也能发送到https上的服务器的...

看看http的通信协议，自己收发消息就是了

			for(int i = 0;i < protocol.length;i++){

			//发送实体数据
			os.write("\r\n".getBytes());
			
			//捕获服务器反馈
			InputStream is = s.getInputStream();
			BufferedReader br = new BufferedReader(
					new InputStreamReader(is));
			String line = br.readLine();
			while(line != null){
				System.out.println(line);
				line = br.readLine();
			}
			//关闭
			br.close();
			is.close();
			os.close();
			s.close();
		}catch(Exception e){
			e.printStackTrace();
		}
	}
}

提示：
HttpConnection 也会采用类似2楼朋友的方式进行调用的哦！！
所以，最终还是2楼的最基础，当然也最难理解！

谢谢楼上的朋友! 但我需要通过http来连接的! 就是用Httpconnection这个类来做的 或HttpClient也可以!
