create session instance

from tornado import ioloop,gen
from tornasess  import SessionCacheFactory

config = {

sess_fac = SessionCacheFactory("redis", config)

#      "port":[4000,5000]
# }
# sess_fac = SessionCacheFactory("memcache", config)
#
#
# or
# config = {"root":"/tmp"}
# sess_fac = SessionCacheFactory("disk", config)
#

session = sess_fac.get_session()

set session data

yield session.start()
session['name'] = 'xxxxx'
session.set("age",100)
session.multi_set({"address":"xxxx","sex":"xxx"})
yield session.end(expires=3600)

get session data

session_id = "GU3ZTM2YTA5ZWViNDE4MTgzM2Q3MzhhMjdjY2IyOWU="
yield session.start(session_id)
session['name']
session.get('name')
session.multi_get(['address','age','name'])

session.delete("name")
del session['age']
yield session.end()
