关于文件下载

Java code

response.setHeader("Content-Type", "application/pdf");response.setHeader("Content-disposition", "attachment;filename="+ filename);

上面2句代码实现了在客户端弹出一个下载的对话框,点击打开,保存的时候都正常,但是当点击取消的时候会报下面的异常:

在网上搜到的原因是服务端正在发送信息,而客户端却终止了接收,所以我想把这个取消按钮屏蔽掉,各位大哥指点下,如何做?

[解决办法]
基本上这个很难，我也经常碰到这个问题
[解决办法]
跟ＬＺ一样，这个我也碰到过，在控制台上有异常信息，但是对用户操作好像没有什么影响而且暂时我也不知道怎么解决，所以放在那放着了。呵呵，大家一起想哈。
