一段Server Push的调试

现在能搜索到的99年最早的在国内介绍Server Push的文章就是自己那篇"Server Push具体实现",今天调试竟然花了很长时间

才正常工作。放在这里做记录吧：

package test;

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;

import javax.servlet.ServletOutputStream;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class Test extends HttpServlet{
public void service(HttpServletRequest request,HttpServletResponse response)
throws IOException
{
ServletOutputStream out = response.getOutputStream();
String strBoundary = "myRandomString";
response.setContentType("multipart/x-mixed-replace;boundary=" + strBoundary);

out.print("--"+strBoundary+"\r\n");
out.print("Content-type: image/jpeg\r\n\r\n");
File f = new File("d:/96.jpg");
byte[] buf = new byte[(int)f.length()];
FileInputStream in = new FileInputStream(f);
in.read(buf);
in.close();
out.write(buf);
out.flush();

try{
Thread.sleep(2000);
}catch(Exception e){}
for(int i = 0; i < 10; i++){
out.print("--"+strBoundary+"\r\n");
out.print("Content-type: text/html\r\n\r\n");
out.print("<script>alert(1)</script>\r\n\r\n");
out.flush();
try{
Thread.sleep(1000);
}catch(Exception e){}
}
out.print("--"+strBoundary+"--\r\n");
}
}
