Why does CoCart use a custom session handler in the first place?

If you’re familiar with WooCommerce, you may be wondering, why using a custom session handler at all instead of the WooCommerce default session handler? A number of reasons but the ones that really matter are.

• The default session handler only supports cookies.
• The default session handler only saves changes at the end of the request in the shutdown hook.
• The default session handler has no support for concurrent requests.
• The default session handler does not support guest customers.
• The default session handler does not store additional data that maybe required to help you.
• More consistent with modern web.
