very new to nhibernate. I'm a little confused on where features should live.

I have the following solution

1) MyProject.Web ( web forms application)

2) MyProject.Domain( class lib) - nhibernate.config - product.hbm.xml

So is it correct I should put the following method in a IHttpModule? ( i can't use a global asax as it's use by the CMS i'm running )

Where should the connectionString live?

HTTPModule in web forms application

 private static ISessionFactory CreateSessionFactory()
        {
            var cfg = new Configuration().Configure(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "nhibernate.config"));
            cfg.SetProperty(NHibernate.Cfg.Environment.ConnectionStringName, System.Environment.MachineName);
            NHibernateProfiler.Initialize();

            return cfg.BuildSessionFactory();

        }

nhibernate.config

   <?xml version="1.0" encoding="utf-8" ?>

NHibernate.Dialect.MsSql2005Dialect NHibernate.Connection.DriverConnectionProvider NHibernate.Driver.SqlClientDriver 16 web NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle
