ERR_RESPONSE_HEADERS_MULTIPLE_CONTENT_DISPOSITION - Duplicate headers received from server issue on chrome

Hi,
 
Recently, in my project while downloading some files(not on all files) i am getting exception on chrome, that say :
 
Duplicate headers received from server

Error 349 (net::ERR_RESPONSE_HEADERS_MULTIPLE_CONTENT_DISPOSITION): Multiple Content-Disposition headers received. This is disallowed to protect against HTTP response-splitting attacks.
 

But when i download the same files on IE, Firefox and other browsers that causing exception, no problem occur it work like charm. 
 
But its weird that why is chrome giving exception only on some files while downloading, then i searched, i found that new release of chrome has this problem. It seem like Content-disposition header become very strict and sensitive, in the spec that chrome uses.
 
Solution that worked for me to solve the problem :
 
Wrong :

response.setHeader(“Content-disposition”, “attachment; filename=${fileName}”)

Correct :

response.setHeader(“Content-disposition”, “attachment; filename=\””+fileName+”\””)
 
It worked for me. Hope it helps you also
