Disallowed Key Characters -Fix

\system\core\Input.php
CODE:
function _clean_input_keys($str)
{
if ( ! preg_match("/^[a-z0-9:_\/-]+$/i", $str))
{
exit('Disallowed Key Characters.');
}
Change to :
function _clean_input_keys($str)
{
$config = &get;_config('config');
if ( ! preg_match("/^[".$config['permitted_uri_chars']."]+$/i", rawurlencode($str)))
{exit('Disallowed Key Characters.'); }

You do not modify Core Classes you extend them!

Think about what is going to happen now if you upgrade the system!

CI version 2.02
clients's cookies name have any problem.

[eluser]InsiteFX[/eluser]
Only in IE! You need to chaange the cookie name from ci_session to cisession

IE doe's not like the underscore character!

Yes, only XP OS with IE.

My config.php (/application/config/config.php)
///
$config['sess_cookie_name'] = 'ci_session';
$config['sess_expiration'] = 7200;
$config['sess_expire_on_close'] = FALSE;
$config['sess_encrypt_cookie'] = FALSE;
$config['sess_use_database'] = FALSE;
$config['sess_table_name'] = 'ci_sessions';
$config['sess_match_ip'] = FALSE;
$config['sess_match_useragent'] = TRUE;
$config['sess_time_to_update'] = 300;
//

Can I change all 'ci_session' to 'ci-session' ?
