Here is an example of a redirect from http to https

when HTTP_REQUEST {
 HTTP::respond 301 Location https://[getfield [HTTP::host] ":" 1][HTTP::uri]
}

 

Here is an example of a redirected website

when HTTP_REQUEST { 
if { [string tolower [HTTP::host]] equals "www.thezah.com" } { 
HTTP::respond 301 Location "https://sales.thezah.com" 
}
 }
