The code is view the attached file of the transaction.
It run just fine at my local computer but when I deployed it at our server, that's when 302 found appears. I can't seem to point where it goes wrong.

Remote Address:192.168.136.7:80
Request URL:http://ptyisrequest-dev/DashBoard/ViewAttachment?filename=2014%5CHW14-1555_AT1.xls
Request Method:GET

Here is the code in my controller:

C#

[Authorize]
[HttpGet]
public FileResult ViewAttachment(string fileName)
{
  var path = tempPath + "\\" + fileName;
  FileInfo file = new FileInfo(path);
  var mimeType = ClassHelper.GetMimeType(file.Name);
  return File(path, mimeType, file.Name);
}

Can anyone tell me how to fix this?

302 means that there is a temporary redirect and that the redirect page was found.

You requested this:
http://ptyisrequest-dev/DashBoard/ViewAttachment?filename=2014%5CHW14-1555_AT1.xls

and the server returned this:
/error/unknown?aspxerrorpath=/DashBoard/ViewAttachment

It looks like the page should be returning a 404 or other error code, but the sites setup means that it just redirects to an error page.

If you can, try to get the error page to emit a more accurate error code and handle it in your method.

If not, check the response code and location. If it is as above then handle the error.

Also, visit the url through a browser and see what error message is on that page.

Hope that helps
