CodeIgniter Session spammed by bots - jimbon - 09-07-2015
hello,
my website has visits from various search engine bots. I would like to ignore the bots from the session table.
i tried with this library https://github.com/donjakobo/codeigniter-clean-sessions but didn't work with ci 3.
Any help?

I'm not sure how well this would work, as it would depend at least somewhat on your site's ability to continue to function without a session, but you could extend the sessions library in a similar fashion to the library you linked by creating a file in /application/libraries/Session/MY_Session.php:
PHP Code:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class MY_Session extends CI_Session
{
public function __construct(array $params = array())
{
$CI = get_instance();
$CI->load->library('user_agent');
if ($CI->agent->is_robot()) {
log_message('debug', 'Session: Robot detected, initialization aborted.');
return;
}
parent::__construct($params);
}
}
This also depends on the ability to access the loader (and, in turn, the user_agent library) at the time the session library is loaded.
Note that this should be the entire contents of the new file. All it does is load the user_agent library to check whether it can identify a robot. If it identifies a robot, it logs a debug message and exits. Otherwise, it turns control back over to the parent, making sure to pass along any parameters which may have been passed by the loader.

Maybe it is a simple solution where you have a blacklist in MY_Session.php:
Code:
<?php
class MY_Session extends CI_Session {
public function __construct(array $params = array())
{
$CI =& get_instance();
$blacklist = [
'123.255.123.255',
'MegaBot',
'Whatever'
];
foreach( $blacklist as $bot )
{
if(
stripos( $_SERVER['HTTP_USER_AGENT'], $bot ) !== FALSE OR
$CI->input->ip_address() == $bot
)
{
return;
}
}
parent::__construct($params);
}
}
