将大字节数组写入输出流的可能影响?

private static void writeData( byte[] file, HttpServletResponse response )
    throws IOException
{
    ....
    // Send the data
    response.setContentLength(file.length);
    response.getOutputStream().write(file);
}

最近,我在IE8中发现一些连接在请求下载文件时会关闭。这是相关的源代码,我想知道是否一次将大字节数组写入响应输出流会导致这个问题。这个问题是非常不可复制的,我经常看到这样的模式:一次写入一定数量的字节,而不是一次写入所有字节,以避免MTU问题,或者类似的问题。

编辑:

我试过用 Cache-Control: no-cache

请求:
