Novice. How would I download all files matching:

<http://www.justice.gouv.fr/bo/*.pdf>

For example, I should be able to retrieve:

<http://www.justice.gouv.fr/bo/2019/20190830/08082019.pdf>

I tried something like this:

httrack <http://www.justice.gouv.fr/bo/*.pdf>

, and I get a 404 error.

Specifying `-F 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:65.0)
Gecko/20100101 Firefox/65.0'` does not resolve the problem.
