1、函数

        String requestedWith = req.getHeader("X-Requested-With");
        boolean isAjax = requestedWith != null ? "XMLHttpRequest".equals(requestedWith) : false;

上面的X-Requested-With是判断是否是ajax还是传统的http请求

if (request.getHeader("x-requested-with") != null    
    && request.getHeader("x-requested-with").equalsIgnoreCase("XMLHttpRequest")) {    
    out.print("该请求是 AJAX 异步HTTP请求。");    
}else{     
    out.print("该请求是传统的 同步HTTP请求。");    
}
