It's extremely common for an HTTP connection to the unqualified first-level domain to direct one to the website home page, but whether that is accomplished by having the IPs be the same or by way of an HTTP redirect, I would not say there's any clear winner. However, it is not a universal practice.
By HTTP I assume you mean by coding on the web page. If so, there is an alternative method, in the configuration file for the virtual domain.
