Redirect to HTTPS with no HTTP site

You could make a wildcard virtual on port 80 and have the iRule generically redirect to the same virtual on https:

virtual generic_http {
   destination 0.0.0.0:80
   mask 0.0.0.0
   ip protocol tcp
   profile tcp http
   rule generic_redirect
}
rule generic_redirect {
   when HTTP_REQUEST {
      if { [HTTP::header exists host] }
         HTTP::redirect https://[HTTP::host][HTTP::uri]
      } else {
         HTTP::redirect https://[IP::local_addr][HTTP::uri]
      }
   }
}

This would allow you to only make the one virtual and rule that generically redirects all http traffic to your https virtuals.
