Also,  if you do not want to feed js to all requests with or without
javascript support (browser js support + javascript actually turned on) you
can do a onload on the first hit that generates a session to ping back to a
sub that sets session->{jssupported} on.   That way you not only know that
the browser supports js,  but it actually has it enabled.  It really
depends on how you are going to construct your pages and fallthrough for
legacy (or secure) browsers.
