How to block a site & all proxy?

[H4CK3R]

Hi,
I want to block all proxy site through htaccess, is it possible?
If yes, then how?
Also, i want to block a site from accessing my site(They are using a bot).
They have a large number of servers and they are changing their server IP at rapid rate. Is it possible to block site not by IP, i.e. by adding deny from www[dot]helloworld[dot]com instead of deny from 123.456.789.000?
Please help in detail.
Thanks.

hi,

You can implement these by installing a proxy servers on your own servers and use the mode_security rules for blocking domain names.

For blocking proxy servers, you might try the following:

How to Block Proxy Servers via htaccess

Basically, using this in the .htaccess file:

# block proxy servers from site access
# http://perishablepress.com/press/2008/04/20/how-to-block-proxy-servers-via-htaccess/

RewriteEngine on
RewriteCond %{HTTP:VIA}                 !^$ [OR]
RewriteCond %{HTTP:FORWARDED}           !^$ [OR]
RewriteCond %{HTTP:USERAGENT_VIA}       !^$ [OR]
RewriteCond %{HTTP:X_FORWARDED_FOR}     !^$ [OR]
RewriteCond %{HTTP:PROXY_CONNECTION}    !^$ [OR]
RewriteCond %{HTTP:XPROXY_CONNECTION}   !^$ [OR]
RewriteCond %{HTTP:HTTP_PC_REMOTE_ADDR} !^$ [OR]
RewriteCond %{HTTP:HTTP_CLIENT_IP}      !^$
RewriteRule ^(.*)$ - [F]

As for denying a domain to access the site, you can use the following:

<Files *>
Order Allow,Deny
Allow from all
Deny from domain.com
</Files>

Please replace domain.com with the domain name that keeps hitting the site.

Will blocking all proxy servers have any negative effects on google or other search engines rankings or crawling of your website?

No, Google doesn't proxy. They just show up. The only thing I've seen that can kill Google is a connection limit that is set too low.
