| # The ServerName directive sets the request scheme, hostname and port that | |
| # the server uses to identify itself. This is used when creating | |
| # redirection URLs. In the context of virtual hosts, the ServerName | |
| # specifies what hostname must appear in the request's Host: header to | |
| # match this virtual host. For the default virtual host (this file) this | |
| # value is not decisive as it is used as a last resort host regardless. | |
| # However, you must set it for any further virtual host explicitly. | |
