How to permanently load a module into web2py ?

[Khalil Khamlichi]

Hello everyone, 

I need to query redis a lot, do I have to import redis on each request ? also I am sedning websocket messages, do I need to import websocket library on every request ? isn"t there any way to load them permanently into web2py ?

Thanks in advance.

perhaps you can import it on models because models is executed for every requests

They are not imported again just because the import is there. Python and web2py's import is smart enough not to re-import a module that was already loaded unless you are using track_changes.

It is OK to run an import statement on every request -- the Python interpreter will only import the module on the first request (per process) -- after that, it will remain in memory.
