Dear Codeigniter team,
reading the questions and answers to this topic does not give me a clear answer.

Can I store more than 4kb of data using a database for the sessions?
Are the contents then stored in a variable instead of cookie?

If you’re using a database to store session data, then yes you can store significantly more than 4KB. The cookie will be storing the session ID which is used to look up the session in the DB table.

Thank you for an answer I can rely on!
