The right plugin for us?

Now we have to split on a cluster the first time and our provider told us to switch with sessions to database stored sessions. Is this the right plugin to reach this goal?

Yep! This plugin is designed exactly for this use case.

Thanks. One more question.
Isn’t WordPress and WooCommerce a Client-side CMS with cookies?

Or does WordPress and WooCommerce really saving sessions in a file on the server like in the wp-content folder? A technical consultant asked me if I’m sure that WordPress isn’t working with client-side cookies.

WooCommerce uses server-side PHP sessions (but they aren’t stored in the wp-content folder).

Where will they be stored?
Can I simulate this change for saving the session in the database even I still have one server (at the moment)? Our new architecture with 2 servers will be ready in the late january. But to test then the first time, is to late.

I just wanna know if this will work for us. Any idea?

Where will they be stored?

Not sure I follow. Where will what be stored?

* WP Native PHP Sessions stores session data in the database.
* Normal PHP sessions are typically stored to the filesystem, although this is configurable.

Can I simulate this change for saving the session in the database even I still have one server (at the moment)? Our new architecture with 2 servers will be ready in the late january.

Yes, this plugin works with single server environments too. You can install and activate it.
