How to force file download in the browser, nginx server

Question

I currently have 2 image locations and they may the formats (jpg,jpeg,png,gif)

i.domain.com/simage.jpg thumbnail
i.domain.com/image.jpg high quality
i.domain         


        

Answer 1

Below config works for me.

server {
    ...
    # Django media
    location /media  {
        alias /var/www/media;  
        types { application/octet-stream .pdf; }
        default_type application/octet-stream;
    }
    ...
}

But the pdf file needs to ends with lowercase pdf for download to work. I still don't know the syntax to add both .pdf and .PDF to above config file. Any suggestion? The answer is based on info from http://210mike.com/force-file-download-nginx-apache/
