PHP session.upload_progress with CodeIgniter

[eluser]Unknown[/eluser]
I'm considering switching to CodeIgniter from Kohana. Kohana doesn't include the PHP session.upload_progress data in their Session class without numerous workarounds or changes to their core. I'm wondering if CodeIgniter can store/read upload_progress data natively in their Session classes?

No, because CodeIgniter uses a session class that doesn't use PHP's native session mechanism. Just like Kohana...
