Do you have memcache installed? mem\_cache\_store uses a memcached server for caching so you will have to start ther server first… On Jun 24, 8:51 am, Fred S. [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) ---

Thanks, I’ve not know about the server, I thought that mem caching allows to store session in application server memory. How can I do that? I just want to get session stored on application server. Should I use :memory\_store?
