I'm trying to prevent other sites from copying my download links, but they're not conventional (they are not formatted at the end), so I can not block through Apache's mod_rewrite.
So I decided to block GET requests from other sites, but the forms I tested are blocking all requests, including the site I'm trying to allow.
What I tried without success was:
<Limit GET>
order allow,deny
Allow from exemplo.com
Deny from all
</Limit>
