phpInfo: What does "Virtual Server" refer to?

I noticed that in phpinfo under "apac开发者_开发问答he2handler", it says:

Virtual Server Yes

What does that refer to? Does that mean that apache is on a virtual (i.e. not dedicated) host? What would be a case when it would say:

Virtual Server No

?

Thanks for any help with this.

That really just means that apache is configured so that it can serve more than one domain. It has nothing to do with whether or not apache is running on a shared server or dedicated server.

Similar terminology, completely different meanings.
