The Apache module is broken up into several sections to address different aspects of an Apache configuration. On the main page, these sections are grouped into Global Configuration and Virtual Servers groups. Using virtual servers it is possible to locate several websites with unique domain names on a single IP address, in order to conserve the rapidly diminishing IPv4 address space.
In the context of the Apache module, Global Configuration refers to configuration-information that will apply to all virtual hosts that are run from the same httpd daemon. It is usually unnecessary to run more than one httpd daemon on a single machine but it is possible. It is also possible to manage more than one such daemon with Webmin via the module cloning feature.
Note | The official Apache documentation [http://httpd.apache.org/docs/] is a good source of additional information about Apache and its modules. |
