Preventing hotlinking at "http" level, not server by server

Server NGINX
1

Hi. There are many code samples on the web for simple hotlinking.

I have some questions on how to do this in a better way, and all my
trial code has not worked, so hope some Nginx guru here can help.

Here’s what I am looking for:

  1. Firstly, I would like the blocking to happen at a server-wide level.
    Nginx is on a dedicated server, and there are many “server” vhost tags
    in a folder. I prefer not to have to write the blocking code for every
    server individually. Is this possible at an “http” level? What’s the
    code for that.

  2. Secondly, I have about 35 domains and many subdomains. I don’t want
    them to be in one long line. But all my “vhost” server tags are inside a
    directory. Can I somehow specify Nginx to allow all those domains whose
    server definitions are in a folder? (/etc/nginx/vhosts)

  3. Will the “IF” condition slow down my Nginx? I remember reading that
    Nginx does not like IF conditions.

  4. I want to allow some additional domains like Google and Facebook and
    Pinterest. What’s a good way to include this in the allowable list.

  5. Finally, if I do have to include this directive in each “server”
    block for each of my domains, can I at least bundle the commands for
    these type of files as such:

`------
location ~* .(png|gif|jpg|jpeg|swf|ico|)$ {
expires 7d;
try_files $uri @backend;

  valid_referers none blocked site.com mysite.com ~\.google\.

~.yahoo. ~.bing. ~.facebook. ~.fbcdn.;
if ($invalid_referer) {
return 403;
}

}

------`

Thanks!
