Hello,
Less a bug, more a matter of understanding:
I thought that the slightly longer response time would allow a scanner to determine that a port is open and in use.
With "https://jsscan.sourceforge.net/jsscan2.html" it seems to be the opposite - it shows all ports as open when I have blocking enabled.
README
Site where you can test if HTTP port scanning works: https://inteltechniques.com/logger/
Is no longer available.
Thank you for your work!
Best regards,
Martin
