CL Scaling for High Traffic Web Sites

Hi,

I'm just curious if these issues are addressed for developing high
traffic web sites in CL:

1) Scaling out: have a distributed in-memory cache (eg. memcached)
that sits between the app and the db.

2) Hardware fail-safe: Make use of the said cache/db to store session
objects.

I remember Marco Baringer mentioned in an old thread that he was going
to implement fast session serialization, which could eventually lead
to these things. Is it available in UCW already? Is it done in other
servers/frameworks?

Thanks!

Bob
