FFUF vhosts/results filtering

Try running a VHost fuzzing scan on ‘academy.htb’ and see what other VHosts you get. What other VHosts did you get?

while responding to this question, gave me a lot of different results

The invalid ones had a size of 986.

I didn’t get why the only valid answer had a size of 0. I don’t get what it means when we have an HTTP response size of 0.

Could you find out anything?
