Instantiating the object into the session scope is fine. However, manipulating the session scope from inside the CFC as per:
<!--- query is loaded to session scope ---> <cfset session.qryAllProducts = qryAllProducts> <cfreturn session.qryAllProducts> is not recommended. This breaks the encapsulation rules usually associated with CFCs. Consider doing this instead: Create a method that queries the DB and saves the query in a property in the VARIABLES scope. Then have the "getter" method return the VARIABLES scoped query. This has the benefit of keeping the query data in the component instead of having to save it separately in the session scope and makes the thing behave like an object with its own properties. It's when the object has these properties that locking can become more important. One technique that works well for instantiated objects is to use a named lock where a UUID forms the name. Create the UUID as part of the init() method and use it for every lock in the component: <cfset VARIABLES.MyLockName = createUUID()> ..... <cflock name="#VARIABLES.MyLockName #" ..... This means that every instance of the component gets a unique lock name, improving performance over full scope locks or a single shared name.
