    After that, yo can replace the host header using an iRule like this.

    when HTTP_REQUEST {
   # Check if requested host starts with subdomain.differentdomain.com
   if { [string tolower [HTTP::host]] eq "subdomain.differentdomain.com" } {
      # Replace the host header value with subdomain.companya.com
      HTTP::header replace Host "subdomain.companya.com"
   }
}

    KR,

    Dario.
