Subject: CGI::Session on mod_ruby

The following script is a simple page counter that works well for me running
as an rhtml file on mod_ruby:

<%
require 'cgi/session'

cgi = CGI.new('html4')

session = CGI::Session.new(cgi)

session['count'] ||= 0
session['count'] = session['count'].to_i + 1

# content must be output in this way in order for headers to be written:
cgi.out { "count: " + session['count'] }

session.close
%>

However, if I replace the line "cgi.out ..." with "puts session['count']"
the script fails incrediment indicating that a new session is being created
every time. I would assume this is because the right headers (cookies,
etc...) are not written out in the response. If you use CGI::Session are you
forced to use cgi.out rather than your own output method?
