Struts2 - Https中IE浏览器不能下载的问题

在http中能下载，但是启用https协议后下载报错问题结果，在谷歌，火狐浏览器正常

具体操作如下：

// 获取下载文件
		//userRegisterInfoPath  下载路径
                File downloadFile = new File(userRegisterInfoPath);
		FileInputStream fos = new FileInputStream(downloadFile);
		byte[] bytes = new byte[4096];
		int read = 0;
		response.reset();
		response.setContentType("application/octet-stream;charset=UTF-8");
                //filename 是带扩展名
		response.setHeader("Content-Disposition","attachment; filename="+ URLEncoder.encode("申请表.pdf", "utf-8"));
		response.setHeader("Pragma", "public");
                //下载设置的关键项
		response.setHeader("Cache-Control","public");  
		ServletOutputStream  sos =  response.getOutputStream();
		while((read=fos.read(bytes))!=-1){
		    sos.write(bytes, 0, read);
		}
		sos.flush();
		sos.close();

<form action="" method="post" enctype="multipart/form-data">
 最大上传2G.
通过 http 协议上传文件(rfc1867协议概述，jsp 应用举例，客户端发送内容构造)
 服务器接收到上传的流，自己其实是不作任何处理的，那个request还是原装的,谁来处理这个request呢,一般采用第三方的工具，这里以commons fileupload为例.
 

DiskFileItemFactory factory = new DiskFileItemFactory();
factory.setSizeThreshold(4096);// 设置缓冲,这个值决定了是fileinputstream还是bytearrayinputstream
factory.setRepository(new File("d:\\temp"));//设置临时存放目录,默认是new File(System.getProperty("java.io.tmpdir"))
ServletFileUpload sfu = new ServletFileUpload(factory);
sfu.setSizeMax(100*1024*1024);//100M
List items = sfu.parseRequest(request);//传入的这个request还是原装的

 见上面的代码，commons fielupload通过ServletFileUpload类的parseRequest(request)方法处理这个原始流。而ServletFileUpload又会调用其爷爷类FileUploadBase的parseRequest(request)方法，然后又会调return parseRequest(new ServletRequestContext(request)),代码如下
