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

This solution will preserve filename AND open file in browser (.net mvc)

Response.Headers["Content-Disposition"] = "inline;filename=\"" + theFile.filename + "\"";
return File(filePath, mimeType);//don't specify filename. It will create second Content-Disposition header
