Changes are made at your own risk and are not guaranteed to work. Always make backups of the database and files prior to implementing hacks. Make a special backup of the file and/or template you are modifying so that you can roll back quickly.
Hacks are dangerous and can cause your site to stop working. They make later updates to ExpressionEngine more difficult; you should track your hacks for post-update re-implementation.
Most hacks are unnecessary, please review the Development Documentation for information on expanding ExpressionEngine via Modules, Extensions, and Plugins.
Hacks are never officially supported.
Question:
How can I exclude certain IPs from being throttled, without disabling throttling all together?
Anwer:
This requires a hack:
Open up core.system.php and find this:
if ($PREFS->ini('enable_throttling') [h3]'y' AND REQ[/h3] 'PAGE')
{
require PATH_CORE.'core.throttling'.EXT;
$THR = new Throttling();
$THR->throttle_ip_check();
$THR->throttle_check();
$THR->throttle_update();
}
What we are going to do is create an array of IP addresses and if an IP is not found in that array, then it does the throttle check:
if ($PREFS->ini('enable_throttling') [h3]'y' AND REQ[/h3] 'PAGE')
[code] {
// GoogleBot (range), MSNBot (full IP)
$pass = array('66.249.71.', '65.54.188.83');
$skip = 'n';
foreach($pass as $value)
{
if (strstr($IN->IP, $value))
{
$skip = 'y';
}
}
if ($skip == 'n')
{
require PATH_CORE.'core.throttling'.EXT;
$THR = new Throttling();
$THR->throttle_ip_check();
$THR->throttle_check();
$THR->throttle_update();
}
}
