NAME ^

CGI::Builder::SessionManager - CGI::Builder / Apache::SessionManager integration

SYNOPSIS ^

   package WebApp;
   use CGI::Builder qw/ CGI::Builder::SessionManager /;

   sub PH_session {
      my $cbf = shift;
      $cbf->page_content = 'Session test page!';
      $cbf->sm->{'foo'} = 'baz';
      $cbf->page_content .= $cbf->sm->{'foo'};
   }

DESCRIPTION ^

CGI::Builder::SessionManager is a CGI::Builder extension that integrates Apache::SessionManager session management into CGI::Builder framework (CBF).

Apache::SessionManager is a mod_perl (1.0 and 2.0) module that helps session management of a web application. This module is a wrapper around Apache::Session persistence framework for session data. It creates a session object and makes it available to all other handlers transparenlty. See 'perldoc Apache::SessionManager' for module documentation and use.

INSTALLATION ^

In order to install and use this package you will need Perl version 5.005 or better.

Prerequisites:

Installation as usual:

   % perl Makefile.PL
   % make
   % make test
   % su
     Password: *******
   % make install

PROPERTIES ^

This module adds sm property to the standard CBF properties.

It's possible to set a value in current session with:

   $cbf->sm->{'foo'} = 'baz';

and it's possible to read value session with:

   print $cbf->sm->{'foo'};   

METHODS ^

sm_destroy

Destroy the current session object.

   $cbf->sm_destroy;

EXAMPLES ^

This is a simple CGI::Builder application, (save it, for example, as /some/path/cgi-builder/WebApp.pm):

   package WebApp;    # your class name
   use CGI::Builder qw/ CGI::Builder::SessionManager /;
   use Data::Dumper;
  
   sub PH_AUTOLOAD {                           # always called for all requested pages
      my $cbf = shift;
      $cbf->page_content = "Default content";  # defines the page content
   }

   sub PH_session {
      my $cbf = shift;
      $cbf->page_content = "Session test!<BR>\n";
      $cbf->sm->{"$$-" . rand()} = rand;
      $cbf->page_content .= '<PRE>' . Dumper($s->cbf) . '</PRE>';
        }

   sub PH_delete_session {
      my $cbf = shift;
      $cbf->page_content = "Session test! (deletion)";
      $cbf->sm_destroy;
   }

and the correspondent configuration lines in httpd.conf:

   <IfModule mod_perl.c>

      PerlModule Apache::SessionManager
      PerlTransHandler Apache::SessionManager

      Alias /cgi-builder "/usr/local/apache/cgi-builder"
      <Location /cgi-builder>
         SetHandler perl-script
         PerlHandler Apache::Registry
         PerlSendHeader On
         PerlSetupEnv   On
         Options +ExecCGI

         PerlSetVar SessionManagerTracking On
         PerlSetVar SessionManagerExpire 1800
         PerlSetVar SessionManagerInactivity 900
         PerlSetVar SessionManagerName CBFSESSIONID
         PerlSetVar SessionManagerStore File
         PerlSetVar SessionManagerStoreArgs "Directory => /tmp/apache_session_data/cbf"
         PerlSetVar SessionManagerDebug 1
      </Location>   

   </IfModule>

In order to test this simple application you must implement the Instance Script that is what is actually called by your web server.

It is a very small, simple file which simply creates an instance of your application and calls an inherited method, process(). Following is the entirely of /some/path/cgi-builder/webapp.cgi:

   #!/usr/local/bin/perl -w
   use WebApp;
   my $webapp = new WebApp;
   $webapp->process();

Restart the httpd server and launch http://localhost/cgi-builder/webapp.cgi .

BUGS ^

Please submit bugs to CPAN RT system at http://rt.cpan.org/NoAuth/ReportBug.html?Queue=CGI-Builder-SessionManager or by email at bug-cgi-builder-sessionmanager@rt.cpan.org

Patches are welcome and I'll update the module if any problems will be found.
