I am using asp.net mvc3, download file in the same browser (Chrome 22). Here is the controller code:
[HttpPost]
public ActionResult Uploadfile(HttpPostedFileBase file)//HttpPostedFileBase file, string excelSumInfoId)
{
...
return File(
result.Output,
"application/vnd.ms-excel",
String.Format("{0}_{1:yyyy.MM.dd-HH.mm.ss}.xls", "????????????", DateTime.Now));
}
On my dev machine I download a programmatically created file with the correct name "????????????_2012.10.18-13.36.06.xls".
Response:
Content-Disposition:attachment; filename*=UTF-8''%D0%A1%D1%83%D0%BC%D0%BC%D0%B8%D1%80%D0%BE%D0%B2%D0%B0%D0%BD%D0%B8%D0%B5_2012.10.18-13.36.06.xls

And from production server I download a file with the name of the controller's action + correct extension "Uploadfile.xls", which is wrong.
Response:
Content-Disposition:attachment; filename="=?utf-8?B?0KHRg9C80LzQuNGA0L7QstCw0L3QuNC1XzIwMTIuMTAuMTgtMTMuMzYu?=%0d%0a =?utf-8?B?NTUueGxz?="

Web.config files are the same on both machines.
Why does filename gets encoded differently for the same browser? Are there any kinds of default settings in web.config that are different on machines that I am missing?
