Before serving the rhtml file to your web client you need to run ERb  
on it and capture the result, then serve it using a different method  
than HTTP::Servlet.

I can't remember the details off-hand but if you look at my Camping  
presentation at http://slides.games-with-brains.net/ you'll find some  
simple examples of rolling WEBrick servers and integrating ERb is  
fairly simple. I usually just add it into the String class as a handy  
instance method:

class String
   def apply_erb
     ERB.new(self).result
   end
end

so when generating the output for the server you'd have a line roughly  
like:

my_content.apply_erb

where my_content is the variable holding the rhtml page text, or a  
method that produces it.
