Thanks for using HTTrack!

retrieves some nodes:

$ find nouveau* -type f | grep 'node/' | head -n 3
nouveaupartianticapitaliste.org/node/40370.html
nouveaupartianticapitaliste.org/node/52353.html
nouveaupartianticapitaliste.org/node/54309.html

But not all. For instance,

<https://nouveaupartianticapitaliste.org/node/2110>

is missing:

$ find nouveau* -type f | grep 'node/2110'
(nothing)

Why?
