I've been using a PHP script to export data from my database (mysql) to a XLS file.
While the file export process is working fine on Firefox and IE.
I am getting errors when trying to export using Google Chrome.
The Google Chrome error is
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_DISPOSITION): Multiple distinct Content-Disposition headers received. This is disallowed to protect against HTTP response splitting attacks.
I need some assistance on this.
Thanks
I've found out what my problem was in the header section of the PHP export code. The incorrect and correct lines are as follows:
Incorrect
header("Content-Disposition: attachment;filename=\"".$this->filename."\"");
Correct
header("Content-Disposition: attachment; filename=\"".$this->filename."\"");
The correction being adding a space between attachment; and filename
Hope this helps.
I had this same problem. However appearing only very rarely. Cause was similar but not quite the same.
Incorrect
header("Content-Disposition: attachment; filename=$filename");
Correct
header("Content-Disposition: attachment; filename=\"$filename\"");
$filename sometimes contained spaces resulting in mentionec Chrome error.
