That rule will work for the TLD (Top Level Domains) .com - and again, if I don't want to get specific about doing "OR" for all the possible TLDs, I think this works, regardless of top level domain:

when HTTP_REQUEST {
  if { ([HTTP::host] matches_regex {^[a-zA-Z0-9]+\.[a-zA-Z]{2,4}$}) } { HTTP::redirect http://www.[HTTP::host][HTTP::uri] } 
}


when HTTP_REQUEST {
  if { ([HTTP::host] matches_regex {^[a-zA-Z0-9]+\.[a-zA-Z]{2,4}$}) } { HTTP::redirect https://www.[HTTP::host][HTTP::uri] } 
}
