Good point Michael. If you want to redirect all requests to HTTPS and prepend www. to hostnames without www. you can modify it: 

when HTTP_REQUEST {
   log local0. "[IP::client_addr]:[TCP::client_port]: [HTTP::method] request to [HTTP::host][HTTP::uri]"
    Check if host doesn't start with www and has at least one alpha character
   if { not ([string tolower [HTTP::host]] starts_with "www") and [string match {[a-zA-Z]} [HTTP::host]] }{
       Redirect to the same host via https with www. prepended
      HTTP::redirect "https://www.[HTTP::host][HTTP::uri]"
      log local0. "[IP::client_addr]:[TCP::client_port]: Redirecting to https://www.[HTTP::host][HTTP::uri]"
   } else {
       Redirect to the same host via https
      HTTP::redirect "https://[HTTP::host][HTTP::uri]"
      log local0. "[IP::client_addr]:[TCP::client_port]: Redirecting to https://[HTTP::host][HTTP::uri]"
   }
}
