CGI::Session just don't work

I got this file to a apache/mod-ruby server and nothing is being set to
"lastaccess"

test.rhtml:
<%
require 'cgi'
require 'cgi/session'
cgi = CGI.new("html4")

sess = CGI::Session.new( cgi, "session_key" => "a_test",
                              "prefix" => "rubysess.")
lastaccess = sess["lastaccess"].to_s
sess["lastaccess"] = Time.now
if cgi['bgcolor'][0] =~ /[a-z]/
  sess["bgcolor"] = cgi['bgcolor']
end

cgi.out{
  cgi.html {
    cgi.body ("bgcolor" => sess["bgcolor"]){
      "The background of this page" +
      "changes based on the 'bgcolor'" +
      "each user has in session." +
      "Last access time: #{lastaccess}"
    }
  }
}
%>

What can be happenning?

A first access cannot have a lastaccess?

Also:

result = "hello"[0]
puts result

if result =~ /h/
  puts 'yes'
else
  puts 'no'
end

--output:--
104
no

No, the OP is correct. In the CGI library, cgi['foo'] is an array. This
is to allow for usage such as /myprogram.cgi?foo=123&foo=456

However, the next line should probably say

    sess["bgcolor"] = cgi['bgcolor'][0]

or else later on,

    cgi.body ("bgcolor" => sess["bgcolor"][0]){

But as to the problem with CGI::Session: I'm afraid it's a very long
time since I bothered with rhtml or CGI, and I'm not sure that mod_ruby
has had much care and attention.

These days I think you'll find that most people write Rack applications
(Rails and Sinatra are both layers on top of Rack), so Rack's
session-handling is much more widely tested.

Deploying a Rails or Sinatra application under Apache is very easily
done with Phusion Passenger.

I'm not seeing that. It's my understanding that cgi handles multiple,
indentical names with cgi.params. For instance, given your url
cgi.params["foo"] would return an array. However, cgi["foo"] would
return the string "123"

However, the next line should probably say

    sess["bgcolor"] = cgi['bgcolor'][0]

or else later on,

    cgi.body ("bgcolor" => sess["bgcolor"][0]){

I'm not even sure what this question has to do with mod_ruby. :frowning:
