Duplicate headers received from the server on displaying pdf in chrome

While transmitting PDF files to Chrome I started getting the following error:

Duplicate headers received from server
The response from the server contained duplicate headers. This problem is generally the result of a misconfigured website or proxy. Only the website or proxy administrator can fix this issue.
Error 349 (net::ERR_RESPONSE_HEADERS_MULTIPLE_CONTENT_

After investing on this issue I noticed the files having comma (,) in their names was causing this issue and was splitting the "content-disposition" header value. The solution was to wrap the file name around quotes (""), like this:

    context.Response.AddHeader("Content-Disposition", string.Format("filename=\"{0}\"", file.FileName));
