Rails4 Dalli ArgumentError key cannot be blank

just run into an odd ArgumentError key cannot be blank error for a shiny Rails4 app with session store config to use memcache store

I've created an app to demo

Thanks in advance.

I had this issue as well. Dalli 2.7.2 fixes the issue(dalli@52f2208), so I recommend upgrading.

We got this error too. Memcached is not down. It happen sometimes on production server and I managed to reproduce it on a pristine rails4 application using dalli_store or mem_cache_store as session_store. Sending a request with a forged blank session_id cookie will raise ArgumentError (key cannot be blank)
