Question about Sessions ...

The database doe's not have a 4kb limit, you can use text, mediumtext and largetext for the user_data field.

The new CI 3.0 session uses blob for the user_data field.

thank you very much.

And on the pedestal these words appear:
'My name is Ozymandias, king of kings:
Look on my works, ye Mighty, and despair!'
Nothing beside remains. Round the decay
Of that colossal wreck, boundless and bare
The lone and level sands stretch far away.
