htaccess difened referrer blocking? Please help!

Hi all,

Does somebody know if it is possible to the following via .htaccess:
I want to block all referrers from a particular TLD, but add an exception for one?
In my case I need to block all the .ru TLDs, while at the same time Yandex.ru is allowed.
Is this possible and if so how (what's the code)?

I can block the unwanted traffic from each domain but this will really take tooooooo long as they are too many!

Thanks in advance

 

Try using apache module mod_authz_host

 

Please can you give me some more details or maybe some example code?
I have no idea what this is

 

One more question if somebody is aware:
Do you think creating a big, very big .htaccess file could be a problem for SEs? I mean smth like 100-200 lines in order to block a number of referrers as well as "bad bots" plus some internal site redirects?
It wont get bigger than few KB, but seems quite long....

 

I don't think it's going to cause any issues, but I don't work for Google so can't tell you that for 100%.

Have a look at this page: http://httpd.apache.org/docs/2.2/howto/access.html this has everything you need to know about accomplishing what you need.
