Force "www." redirect if missing from HTTPS requests

For this kind of a rule all you'd need is something like:

when HTTP_REQUEST {
  if { ! ( [HTTP::host] starts_with "www." ) } {
    HTTP::redirect "https://www.[HTTP::host][HTTP::uri]"
  }
}

Keep in mind, though, that you'll have to have a Client SSL profile assigned to this Virtual, which will decrypt the data to allow TMoS to inspect it.

HTH,
