Ejemplo hacking metodo put http

Hola, estoy realizando una auditoría de un servidor que tiene habilitado el metodo HTTP/1.1 PUT:

# nc -vv www.prueba.com 80

Intentamos subir un fichero de prueba con curl -T

Ejecutamos curl con -H Expect: para evitar el Expect header

curl -H Expect: -T prueba.html www.prueba.com/

No hay manera de subir el fichero aun teniendo el método PUT activado, alguien sabe por que podría ser ?¿?
