Codeigniter Clean Session Library

Codeigniter drop in for keeping your ci_sessions clean of bots (to reduce inserts).
If you run a site that has a high frequency of bots hitting it, you will notice your session table grow.

Eliminate bots from showing up in your sessions by simply dropping this into your /application/library folder.

Load your library the standard way (autoload for instance):

$autoload['libraries'] = array('session');

and lastly, update your /application/config/user_agents.php file to include any new bots you want to block:

// There are hundreds of bots but these are the most common.
$robots = array(
	'googlebot'		=> 'Googlebot',
	'msnbot'		=> 'MSNBot',
	'baiduspider'	=> 'Baiduspider',
	'bingbot'		=> 'Bing',
	'slurp'			=> 'Inktomi Slurp',
	'yahoo'			=> 'Yahoo',
	'askjeeves'		=> 'AskJeeves',
	'fastcrawler'	=> 'FastCrawler',
	'infoseek'		=> 'InfoSeek Robot 1.0',
	'lycos'			=> 'Lycos',
	'yandex'		=> 'YandexBot'
);
