I hope this gets in on 2.7 though it has been feature freezed 😟

I'm pretty sure there already exists a redis session handler, even as PHP C extension.

@Tobion please have a closer look. This is just a wrapper which internally uses the C extension. Youcan set the session handler on a PHP configuration level but often it is more convenient to place it right into your app. That's why all other handlers were created in the first place.

@sgrodzicki I had a close lock and I don't see the point of it.

1. it's not compatible with the core redis session handler, as it for example uses a different prefix by default. so you cannot easily exchange them
2. it has less features then the existing one
3. it doesn't seem to lazy connect to redis
4. it doesn't close the connection

So what's the advantage?

When do you think it's more convenient to use a custom handler, instead of the native one?

@jakzal when you don't have access to the PHP configuration file and/or you're hosting multiple Symfony projects on the same server/workers.

@sgrodzicki you can set the native handler in code with ini_set. You don't need access to the config file.

@Tobion how is that different from Memcached/MongoDB?
