Hello,

HTTP TRACE method is enabled on your server which should not be enabled. It can lead to cross site tracing ! I think this is not a critical issue but I thought I will still report because it is always better to fix it :)

Cross site tracing: https://www.owasp.org/index.php/Cross_Site_Tracing

$ curl -X TRACE http://aspen.io -vv                                                                                                        [19:57:58]
