Even if you say
import myclass
in the controller and this statement is executed at every request, the
module is imported and it runs only once. If you put initialization code in
the module it will run only the first time. You can do:
# in myclass.py
initialized = False
# end
# in controller
import myclass
if not myclass.initialized:
...
myclass.initialized = True
# end
and make sure the initialization code is thread safe.
