Memcached PHP Sessions

[Jeremy Blain]

Memcached should not be used for data that must be saved. 

If losing a few/alot/all your sessions or getting so many sessions that
they keep getting pushed out of the cache is ok, then great.  But if
not, memcached is probably not the solution. 

Check the archives for the list, there has been alot of discussion about
the pros/cons of session handling with memcached.
