Symfony 2.1.2 memcache session kinda SSO

Question

I'm kinda lost in all the session stuffs in Symfony. I'm gonna explain what I want to achieve and I only want to be pointed out on the right track.

I have PHP session stored in memcache (I don't have choice due to past systems). And in my Symfony site I have to plug it in memcache too, no problem here. But before starting a session I have checks to do to see if my user already has a session in memcache from another site to get informations ... and then set my session id to this one.

I've tried to extend Session, but it seems it's not the right place to do so.

Any hint would be greatly appreciated.

Answer 1

I tried to implement this solution with memcache. As far as I can see, it works but I can't find any session related data set in my memcache server. But it seems to be a good starting point for working ;-) Also interesting is the documentation of all default values for the framework configuration (app/config/config.yml) in the sf2 docs. Maybe that helps :-)
