How to handle sessions with multiple servers?

[StefanKittel]

Hello,

i want to create a cluster to host presta in the current version.

The cluster contains 4 server:
- Load Balancer, memcached
- DB Server
- Webnode 1
- Webnode 2

So i need to change session handling to use memcache.
I found no settings in presta.

When I change the session.save_handler in the php.ini it looks fine in the frontend, but the backend craches.
{"exception":"[object] (RuntimeException(code: 0): Failed to start the session at /var/www/share/shop/vendor/symfony/symfony/src/Symfony/Component/HttpFoundation/Session/Storage/NativeSessionStorage.php:146)"

So how to change the session handling in presta to memcached?

Stefan
