If so remove it. That site requires valid forward_for: wget --header='X-Forwarded-For: 192.168.1.1' -S -O /dev/null www.prefettura.it # WORKS wget -S -O /dev/null www.prefettura.it # WORKS wget --header='X-Forwarded-For: unknown' -S -O /dev/null www.prefettura.it # NOT WORKING Maybe they are checking that value.... Better yet is to use header acl to remove that header to that specific site... Best regards, Nuno Fernandes
