Block Proxy Servers from accessing the website

Block proxy servers by HTTP protocols. If you don’t want to purchase software, there is another way. You can insert a script in your website’s root htaccess file. It’s best to copy and paste the code, rather than type it. That way, you can be sure that you won’t make any errors. After you’ve inserted the code, upload it to your server. This method is effective. Insert the following code:
paste the below entries in .htaccess file

====================
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]
