下午结帖～～～有关Servlet返回xml的缓存问题～～～在结等

Question

利用AJAX向servlet发送请求返回xml,再在客户端处理xml文件．Servlet端返回的xml缓存始终无法解决．现在的代码如下：
PrintWriter out = response.getWriter();
response.setContentType("text/xml; charset=UTF-8");
Calendar objCal1 = Calendar.getInstance();
Calendar objCal2 = Calendar.getInstance();
objCal2.set(1970,0,1,0,0,0);
response.setDateHeader("Last-Modified",objCal1.getTime().getTime());
response.setDateHeader("Expires",objCal2.getTime().getTime());
response.setHeader("Cache-control", "no-cache" );
response.setHeader( "Pragma", "no-cache" );

Answer 1

我的就写了这样一句话就好了        response.setContentType(CONTENT_TYPE);
        response.setHeader("Cache-Control","no-cache");不知道你的是什么现象。

Answer 2

response.setContentType("text/xml; charset=UTF-8");///必须要
response.setHeader("Cache-Control","no-cache"); ////必须要
try{
PrintWriter out = response.getWriter();

out.println( dao.getJGPeopleString(jg) );

out.close();

}catch(Exception e)
{
System.out.println("InSelectPropleAction."+e.toString());
}
