Chrome, pdf display, Duplicate headers received from the server

Question

I have a section on a website where I display a pdf inside a light box. The recent chrome upgrade has broken this displaying:

Error 349 (net::ERR_RESP

Answer 1

I was having the same issue and fixed it by just removing the file name from the return statement.

Change:

 return File(outStream.ToArray(), "application/pdf", "Certificate.pdf");

to:

 return File(outStream.ToArray(), "application/pdf");

And KEPT the:

Response.AddHeader("content-disposition", "attachment;filename=\"" + "Certificate.pdf" + "\"");

This still keeps the name for the downloaded file.
