I am using this code to serve a file for download via PHP:
$file='file.pdf';
$filepath="/path-to-download-folder/$file";
if(!file_exists($filepath)){
header('HTTP/1.1 404 Not Found');
exit;
}elseif(!is_file($filepath) or !is_readable($filepath)){
header('HTTP/1.1 403 Forbidden');
exit;
}else{
header('Cache-Control: no-store, no-cache, must-revalidate');
header('Content-Type: '.mime_content_type($filepath));
header('Content-Length: '.filesize($filepath));
header('Content-Disposition: attachment; filename="'.$file.'"');
set_time_limit(0); // Big files/slow connections may result in incomplete downloads
readfile($filepath);
exit;
}
However some people are receiving a corrupted PDF file.
For example: http://mlkshk.com/r/8FGS
In Nginx I have this:
gzip on;
gzip_disable "msie6";
# gzip_vary on;
# gzip_proxied any;
# gzip_comp_level 6;
# gzip_buffers 16 8k;
# gzip_http_version 1.1;
# gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;
My question is: how to set it not to gzip PDF files? Maybe this is the problem...
Thanks.
