Hi LiteSpeed, My site is in heavy load condition now. But the anti-ddos feature does not work efficiently. The attachment is my log file. It seem that LiteSpeed cannot detect the IP 18.104.22.168 as the ddos IP. LiteSpeed is a great webserver, i hope you can improve the Anti-DDOS Block feature. I suggest the feature to add the denied IPs without tell us to restart LiteSpeed. Thanks.
