    Hi SteveEason,

    string tolower: Returns lowercase value.

    when HTTP_REQUEST {
	if { [string tolower [HTTP::host]] contains "code1"} {
		HTTP::redirect "https://www.newwebsite.com/Code1&fcRedirect=true"
	}
	elseif { [string tolower [HTTP::host]] starts_with "code2"} {
		HTTP::redirect "https://www.newwebsite.com/Code2&fcRedirect=true"
	}  
	elseif { [string tolower [HTTP::host]] starts_with "code3"} {
		HTTP::redirect "https://www.newwebsite.com/Code3&fcRedirect=true"
	}
	else {
		HTTP::redirect "https://www.newwebsite.com[HTTP::uri]&fcRedirect=true"
	}
}

    switch version:

    when HTTP_REQUEST {
	switch -glob [string tolower [HTTP::host]] {
		"*code1*" { HTTP::redirect "https://www.newwebsite.com/Code1&fcRedirect=true" }
		"*code2*" { HTTP::redirect "https://www.newwebsite.com/Code2&fcRedirect=true" }
		"*code3*" { HTTP::redirect "https://www.newwebsite.com/Code3&fcRedirect=true" }
		default { HTTP::redirect "https://www.newwebsite.com[HTTP::uri]&fcRedirect=true" }
	}
}

    If codeX tags are contained in uri instead of host, you should use [HTTP::uri] instead of [HTTP::host].

    when HTTP_REQUEST {
	switch -glob [string tolower [HTTP::uri]] {
		"*code1*" { HTTP::redirect "https://www.newwebsite.com/Code1&fcRedirect=true" }
		"*code2*" { HTTP::redirect "https://www.newwebsite.com/Code2&fcRedirect=true" }
		"*code3*" { HTTP::redirect "https://www.newwebsite.com/Code3&fcRedirect=true" }
		default { HTTP::redirect "https://www.newwebsite.com[HTTP::uri]&fcRedirect=true" }
	}
}
