NHibernate SessionFactory

I just want to have this confirmed :

When working with NHibernate, I am expected to get a session from the session factory for each开发者_如何学运维 operation, right ?

What's your definition of 'operation' ? You can perform multiple actions within one session. You should see the session as a unit of work.

One session per transaction. For example one session per web-request in web-application.

A good practice is to put the SessionFactory stuff into Global.asax
