Both of these options can occur more than once within a block and are handled based on
the Order setting. Setting Order to Deny,Allow permits access to any host that is not listed in a
Deny directive. A setting of Allow,Deny denies access to any host not allowed in an Allow directive.
Like most other options, the most specific Allow or Deny option for a host is used, meaning that
you can Deny access to a range and Allow access to subsets of that range. By adding the Satisfy
option and some additional parameters, you can add password authentication. For more information
about access control, see http://httpd.apache.org/docs/mod/mod_access.html.
Location blocks (in the generic sense) can be enclosed within a VirtualHost block. Virtual hosts,
which are described in greater detail in the next section, are a convenient (and almost essential)
tool for altering server behavior based on the server address or name that a request is directed to.
Most global configuration options are applied to virtual hosts but can be overridden by directives
within the VirtualHost block.
