the following program with fail both the way it is, and using the commented
section:
~ > cat a.cgi
#! /usr/local/bin/ruby
require 'cgi'
require 'cgi/session'
cgi = CGI::new
database_manager = CGI::Session::FileStore
session =
=begin
begin
s = CGI::Session::new cgi, 'database_manager' => database_manager, 'new_session' => false
s.delete
s
rescue ArgumentError
CGI::Session::new cgi, 'database_manager' => database_manager, 'new_session' => true
end
=end
CGI::Session::new cgi, 'database_manager' => database_manager
session.close
this_time = Time::now
last_time = session['last_time'] || this_time
session['last_time'] = this_time
session.close
content = ''
content << "<hr> THIS_TIME @ <b>#{ this_time }</b> <hr>"
content << "<hr> LAST_TIME @ <b>#{ last_time }</b> <hr>"
cgi.out{ content }
in either case a new session is __always__ created. the docs say:
...
# A CGI::Session instance is created from a CGI object. By default,
# this CGI::Session instance will start a new session if none currently
# exists, or continue the current session for this client if one does
# exist. The +new_session+ option can be used to either always or
# never create a new session. See #new() for more details.
...
so there is no way to re-use a session attm. this seems serious. i think this
patch addresses the issue:

end
and, indeed, with the change the following works as expected/doccumented:
#! /usr/local/bin/ruby
require 'cgi'
require './cgi/session'
cgi = CGI::new
content = ''
database_manager = CGI::Session::FileStore
this_time = Time::now
begin
session = CGI::Session::new cgi, 'database_manager' => database_manager
last_time = session['last_time'] || this_time
session['last_time'] = this_time
session.close
content << "<hr> THIS_TIME @ <b>#{ this_time }</b> <hr>"
content << "<hr> LAST_TIME @ <b>#{ last_time }</b> <hr>"
rescue Exception => e
m, c, b = e.message, e.class, e.backtrace.join("\n")
content << "<pre>#{ m } (#{ c })\n#{ b }</pre>"
end
cgi.out{ content }
hopefully this hasn't already been fixed - i searched for a while....
regards.
