How to block a bot by User Agent Sting
Do you have those bandwidth hogging bots as much as Phil and I do? Did you know you can block them in your .htaccess file?
Block the BOT
Let block the most annoying bot on the internet - Baidu spider
vim .htaccess
Now Add the following to block
RewriteEngine On RewriteCond %{HTTP_USER_AGENT} Baiduspider [NC,OR] RewriteCond %{HTTP_USER_AGENT} Baidu [NC] RewriteRule ^.*$ - [F,L]
That's it save the file, and you are now blocking the Baidu spider
Testing to see if its blocked
One way to do this is to use curl
curl -I http://www.briansnelson.com -A "Mozilla/5.0 (compatible; Baiduspider/2.0; +http://www.baidu.com/search/spider.html)"
Now you will get a 403 Forbidden
