28 | * Perform regular expression matches on the body of | |

30 | * of the test indicates whether or not a match | |
31 | * is expected. If the server returns a <i>null</i> | |
32 | * (e.g. in the case of an empty HEAD response), the | |
33 | * validator will always fail, regardless of the setting | |
