How to set hashlimit in iptables to protect website from http flood?

Question

iptables

Hello. There was a task to protect the website from http-flood by means of iptables. Namely hashlimit (maybe something else?). What parameters need to be selected so that legitimate connections pass, and attempts to flood the site with left requests are cut off?
