in thread having problems w/CGI-Session

No confusion :) Please allow me to explain:

When I first wrote programs that used CGI::Session, I made the same mistake that I describe. . . I accidentally created a new session every time my program ran. Or, to look at it another way, every time the browser made a request of my script on the webserver, a new session was created. Once I realized what I had done, it was an easy thing to fix.

What I do struggle to understand is why his script appeared to work on Apache but not on iServer. As I never intend on using iServer I don't care all that much either ;) Whether or not it's some sort of bad coincidence or conclusion, or whether its a program bug or configuration issue is impossible to tell unless we get some code though ;) (and at this point I'm doubting that will ever surface).

Happy weekend!

    Oh, ye of little faith. :-P

    Here's the code for the 'initialize_session' method that's called from the 'cgiapp_init' method of the '' module that's inherited from 'CGI::Application':

    sub initialize_session
    my $self = shift;
    my $q = $self->query();

    my $session = CGI::Session->new('driver:File',
    $q->cookie('CGISESSID') || $q->param('CGISESSID') || undef,
    { Directory=>'/ctrlacc/lhdsurv/session/mid_yr_rpt_survey' } )
    or die($CGI::Session::errstr);

    # 05-17-2005: See if following code works
    # expire the session itself after 1 idle hour

    #Initialize the session and get the id.
    my $sessionid = $session->id();

    if ( (! defined($q->cookie('CGISESSID'))) or
    ($sessionid ne $q->cookie('CGISESSID')) )
    # If the session has expired, reset the cookie
    $self->header_add(-cookie => $q->cookie(-name => 'CGISESSID', value => $sessionid, -path=>'/') );
      Thank you, I like being mistaken in that way :)

      You might want to consider using CGI::Application::Plugin::Session. All that code you have could be boiled down to the following:
      use CGI::Application::Plugin::Session; my %options = ( Directory => "/ctrlacc/lhdsurv/session/mid_yr_rpt_survey" ); $self->session_config( CGI_SESSION_OPTIONS => [ undef, $self->query, \%options ], SEND_COOKIE => 1, );
      and it would be more readable. I typically throw that in the cgiapp_init() method of my CGI::Application base class, but if you wanted to throw it in it's own function it's probably alright.

      And I've never had any luck setting expiration times with CGI::Session. They never work for me. Either don't expire the cookie, or set it to expire as soon as the browser closes.

      Good luck, I hope this helps!
