[root@localhost html]# curl http://a0.awsstatic.com/test.html --header "Host: d36niw3noxy6zx.cloudfront.net"
snappyjack

查找高信誉域名

for i in {a..z}; do for j in {0..9}; do wget -U demo -q -O - http://$i$j.awsstatic.com/test.html --header "Host: d36niw3noxy6zx.cloudfront.net" && echo $i$j; done;done

结果

[root@localhost html]# for i in {a..z}; do for j in {0..9}; do wget -U demo -q -O - http://$i$j.awsstatic.com/test.html --header "Host: d36niw3noxy6zx.cloudfront.net" && echo $i$j; done;done
