ERR_RESPONSE_HEADERS_MULTIPLE_CONTENT_DISPOSITION error in Chrome - How to fix
Today we were called to fix a strange issue that was happening to one of our colleagues when trying to download a PDF file from one of our Document Management Systems. The error was related to a single file and sounded like this: This page isn't working (the website) sent an invalid response. ERR_RESPONSE_HEADERS_MULTIPLE_CONTENT_DISPOSITION
That sounded quite strange, especially considering the fact that a lot of other files - same extension, same size and so on - was working fine. We found the solution rather quickly by finding this StackOverflow thread, which luckily enough pointed us to the right direction. The issue was related to a single "comma" in the filename as defined in the Content-Definition header, which was unescaped: Response = 'attachment; filename=file,name.pdf'; It's worth noting that, even if the mentioned SO topic was related to Django, it's definitely an universal issue: we were getting it with ASP.NET C# as well. Anyway, the proper solution was to escape the filename using double quotes, thus avoiding HTTP header mismatches: Response = 'attachment; filename="file,name.pdf"'; That's pretty much about it. I hope that this quick fix will help those who'll be stuck with this issue as well! Read the full article
