Hello,

I have an http2 application fuzzing workflow where I need to set the host header to a specific value (the same analogy of a vhost),
as an example:
ffuf -u <url_x_domain> -request req.raw -http2 -w wordlist:FUZZ the req.raw contains Host: y_domain
or
ffuf -u <url_x_domain> -X POST -d "p=FUZZ" -http2 -w wordlist:FUZZ -H "Host: y_domain"

if the y_domain set to something like example.com/hello
ffuf will complain about "invalid http2 host header"
for information tools like burpsuite supports exactly the intended behavior but not enough performance for my need.

Thank you.
