How can I block a referer (semalt) across my Apache server?

  • 772

semalt is a pretty annoying company. I'd like to keep them off my servers (and out of my analytics).

Here it shows how to block them through .htaccess like this:

SetEnvIfNoCase Via evil-spam-proxy spammer=yes
SetEnvIfNoCase Referer evil-spam-domain.com spammer=yes
SetEnvIfNoCase Referer evil-spam-keyword spammer=yes
SetEnvIfNoCase Via pinappleproxy spammer=yes
SetEnvIfNoCase Referer semalt.com spammer=yes
SetEnvIfNoCase Referer poker spammer=yes

Order allow,deny
Allow from all
Deny from env=spammer

I'd rather handle do this once and for all in my /etc/apache. How can I do that?

  1. Quoted from from the manual on .htaccess files:

    You should avoid using .htaccess files completely if you have access to httpd main server config file. Using .htaccess files slows down your Apache http server. Any directive that you can include in a .htaccess file is better set in a <Directory> block, as it will have the same effect with better performance.
