Answer 1

A little mixing did the job for me. Forced to download a CRX file instead of installing or displaying.

## Download crx
location ~* \.crx$ {
    add_header Content-disposition "attachment; filename=$1";
}

Answer 2

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/

Answer 3

I have been trying to get this functionality into my own nginx server.

I have a folder on server that I would like to have open for anyone who knows the path.

To do that I added a /file/ location into my nginx config file.

server {
   listen 80;
   server_name example.com;

   location /file/ {
       alias /var/openStuff/file/;
       add_header Content-disposition "attachment";
   }
}

Any request to example.com/file/x will go to /var/openStuff/file and look for x and force the browser to download the file

This will also work if the path is /file/stuff/things.txt and will serve it from /var/openStuff/file/stuff/things.txt

You just need to return HTTP header Content-disposition:

location ~* /orig/(.+\.jpg)$ {
    add_header Content-disposition "attachment; filename=$1";
}
