Create or extend a Web application

Note: Visit www.microsoft.com for the most up-to-date and comprehensive information.

When you create a new Web application, you also create a new database and define the authentication method used to connect to the database.

To have separate IIS Web sites that expose the same content to users, extend an existing Web application. This is typically used for extranet deployments in which different users access content by using different domains.
