It seems like this is not working:
server_name blabla.bla;
location ~* (wp-comments-posts|wp-login)\.php$ {
if ($http_referer !~ ^(http://$servername) ) {
return 405;
}
}
While
server_name blabla.bla;
location ~* (wp-comments-posts|wp-login)\.php$ {
if ($http_referer !~ ^(http://blabla.bla) ) {
return 405;
}
}
works just fine. Is this expected and if so why? Or am I doing something wrong here?

If you have the referer module you might like this one, this will ONLY allow the current server names to be valid referrers. All others will return as 405 error.
location ~* (wp-comments-post)\.php$ {
valid_referers server_names;
if ( $invalid_referer ) {
return 405;
}
