nope. only the one pertaining to the application.
https://github.com/web2py/web2py/blob/master/gluon/contrib/redis_cache.py#L265
that being said, I **think** that the issue may be indeed that the
RedisCache instance is istantiated at the first access. This never happened
to me (heavy redis user here :-P) because I have only one app per redis
host.
I'd argue that a fix **can** be
(https://github.com/web2py/web2py/blob/master/gluon/contrib/redis_cache.py#L68
and following)
locker.acquire()
try:
instance_name = 'redis_instance_' + current.request.application
if not hasattr(RedisCache, instance_name):
setattr(RedisCache, instance_name, RedisClient(*args, **vars))
return getattr(RedisCache, instance_name)
finally:
locker.release()
let me know if it fixes the problem.
