LTM iRule to redirect root domain to cname?

Doing some research and finding the inverse of this request.

Is it possible to have an iRule to redirect traffic destined for the root domain to a cname value?  Example-

website.com -> www.website.com

This VIP ultimately resolves to several external root domains, so ideally looking for something that would function for multiple domains.

website1.com -> www.website1.com
website2.com -> www.website2.com
website3.com -> www.website3.com

Thank you!

    If my assumption is correct that you're looking for an HTTP redirect here, this would be most simply:

     

    when HTTP_REQUEST {
  if { [llength [split [HTTP::host] "."]] == 2 } {
    HTTP::redirect https://www.[HTTP::host]
  }
}
