I have a LAMP + Wordpress server that I access with the IP address only. I don't plan on getting a domain name for the server.
I want to know if it is possible to prevent hotlinking of resources if my server doesn't have a domain name?
Right now I configured my .htaccess like below, but it doesn't seem to be working.
IndexIgnore */*
php_flag zlib.output_compression Off
RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://(.+.)?11.22.33.44/ [NC]
RewriteRule \.(zip|gif|jpg|js|css|png)$ - [F]
Edit to add for @JennyD:
I checked the access.log and couldn't see a referrer.
My apache2.conf defines a custom log format called 'combined':
LogFormat "%h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" combined
In my sites-enabled, the 'combined' access log format is used by the directive:
CustomLog ${APACHE_LOG_DIR}/access.log combined
This is what my access.log is showing:
