Re: Good storage/system for sessions

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

We are using MongoDB in our latest projects for storing data changing
frequently (e.g. session-like data). We have been using Memcached in the
past occasionally. In both cases you may need to write a bit of code for
integration both systems with the ZODB transaction system (if needed) -
writing a ZODB transaction handler is pretty easy.
