Hi Yan,

1. string map

when HTTP_REQUEST {
	if { [HTTP::host] starts_with "www." } {
		HTTP::redirect https://[string map {www. ""} [HTTP::host]][HTTP::uri]
	}
}

2. string range

when HTTP_REQUEST {
	if { [HTTP::host] starts_with "www." } {
		HTTP::redirect https://[string range [HTTP::host] 4 end][HTTP::uri]
	}
}

3. getfield

when HTTP_REQUEST {
	if { [HTTP::host] starts_with "www." } {
		HTTP::redirect https://[getfield [HTTP::host] "www." 2][HTTP::uri]
	}
}

4. substr

when HTTP_REQUEST {
	if { [HTTP::host] starts_with "www." } {
		HTTP::redirect https://[substr [HTTP::host] 4][HTTP::uri]
	}
}
