Issue In Download CSV File In IE8 In Https

[Amitabhk Pandey]

Dear Team,

I facing on issue while downloading CSV file in IE.
I am downloading csv file on a server location and then passing that file path to download the same.
Below is the code

DOWNLOAD_DIRECTORY ="D:\\Newgen_Upload\\Dispatch_Download_"+curDateTime+".csv";
		getReport(sCabname,sSessionId,sJtsIp,iJtsPort,sUserName,DOWNLOAD_DIRECTORY);
		response.setContentType("application/octet-stream");
		response.setHeader("Content-Disposition","attachment;filename=downloadfilename.csv");
		FileInputStream fileIn = new FileInputStream(DOWNLOAD_DIRECTORY);
                                ServletOutputStream out1 = response.getOutputStream();		
		byte[] outputByte = new byte[4096];
		while(fileIn.read(outputByte, 0, 4096) != -1)
		{
			out1.write(outputByte, 0, 4096);
		}
		fileIn.close();
		out1.flush();
		out1.close();

This code is not working in IE when i use https url but works in case of http(means csv file gets downlaod).On click of download,the jsp file getting downloaded.
In Chrome csv file getting download but html code is coming in csv file.

Server is Weblogic12C with https.
