https导致servlet无法下载文件5

servlet代码如下： [code="java"] String filename = file.getName(); //String ext = filename.substring(filename.lastIndexOf(".") + 1).toUpperCase(); InputStream fis = new BufferedInputStream(new FileInputStream(filePath)); byte[] buffer = new byte[fis.available()]; fis.read(buffer); fis.close(); resp.reset(); resp.setCharacterEncoding("utf-8"); // resp.setHeader("Expires", "0"); // resp.setHeader("Pragma", "public"); //resp.setHeader("Cache-Control", "public"); // resp.setHeader("Cache-Control", "must-revalidate, post-check=0, pre-check=0"); // resp.setHeader("Cache-Control", "cache, must-revalidate"); resp.setHeader("Content-Disposition","attachment;filename="+ new String(filename.getBytes("iso8859-1"),"utf-8")); resp.setHeader("Content-Length", "" + file.length()); resp.setContentType("application/octet-stream"); // resp.setContentType("application/x-msdownload"); // resp.setContentType("application/x-download"); OutputStream os = new BufferedOutputStream(resp.getOutputStream()); os.write(buffer); os.flush(); os.close(); [/code] 如果用的是http的话就可以下载，但是用https就执行完servlet后就没弹出下载提示框，无法下载，注释的代码试过也没用。试过用重定向到"http://localhost:8080/MyServlet/DownloadServlet"也不行，因为是在别的平台上做二次开发，必须得用https，请问大家有没有什么办法？

问题补充：String filename = file.getName();
//String ext = filename.substring(filename.lastIndexOf(".") + 1).toUpperCase();

InputStream fis = new BufferedInputStream(new FileInputStream(filePath));
byte[] buffer = new byte[fis.available()];
fis.read(buffer);
fis.close();

resp.reset();
resp.setCharacterEncoding("utf-8");

//resp.setHeader("Expires", "0");
//resp.setHeader("Pragma", "public");
//resp.setHeader("Cache-Control", "public");
//resp.setHeader("Cache-Control", "must-revalidate, post-check=0, pre-check=0");
//resp.setHeader("Cache-Control", "cache, must-revalidate");
resp.setHeader("Content-Disposition","attachment;filename="+ new String (filename.getBytes("iso8859-1"),"utf-8"));

resp.setHeader("Content-Length", "" + file.length());
resp.setContentType("application/octet-stream");
//resp.setContentType("application/x-msdownload");
//resp.setContentType("application/x-download");
OutputStream os = new BufferedOutputStream(resp.getOutputStream());
os.write(buffer);
os.flush();
os.close();
