<aside> 💡 It sends both HTTP (80) and HTTPS (443) requests. It does not matter what the status code is. If its 300, 400 or 500, we just wants to know if it responds or not and if it responds it tells us that its alive here.

</aside>

To send only HTTPS (443) requests

cat tesla.xom/recon/final.txt | httprobe -s -p https:443

-s: Remove all the default ports which is 80, 443

To strip off the https from the front

cat tesla.com/recon/final.txt | httprobe -s -p https:443 | sed ‘s/https?:////’

To strip off the 443 from the end

cat tesla.com/recon/final.txt | httprobe -s -p https:443 | sed ‘s/https?:////’ | tr -d ‘:443’
