i did some grepping of my code and found some things....
- it seems that cache.ram is automatically set to GAE memcache when you
are using GAE. it's part of the GAE setup web2py does for you.
- the code above looks OK for storing sessions in memcache. FWIW, I gave
up using memcache for sessions because the eviction time was too short for
my need on GAE (about 5 mins was the best i could get)
I am using memcache on GAE quite a bit, so it for sure can work. Can you
post the stack trace from the GAE logs (SDK or production) that you are
seeing?
thanks,
cfh
