What you have works and is fine for simple setups like yours.

However, since you ask for "proper" ...

Recommended practice when you have same-type data and ACLs used in
identical ways like these ones. Is to place both those domain values in
the one ACL named 'www'. That will simplify your access lines.

There are some tiny memory and (cumulative) speed gains. But the biggest
reason is easier understanding and maintenance of the config if/when it
gets more complex.
