30 | * This handler manages the allowed and denied extensions for each resource | |

33 | * <p> | |
34 | * <em>Hint</em>: It's recommend to use either allowed or denied extensions for | |
35 | * one file type. <strong>Never</strong> use both at the same time! That's why | |
36 | * denied extensions of a file type will be deleted if you set the allowed one | |
37 | * and vice versa. | |
