In response to delete session using CGI::Session I put together a snippet which uses CGI::Session to delete expired session files. It suffers from the unfortunate side effect that the last access time will be updated for un-expired sessions.

This new snippet below solves that problem by not using CGI::Session at all. However, it assumes that you're using the default serialization method and the default file naming scheme.

Note: it has been minimally tested on my part. It's probably not suitable for use in a production environment in its current state.

update, (10/09/2003): added "or die" to open. Fixed eval(). Tested w/ perl 5.8.0 on win2k.

use strict;
use File::Find;

use constant SESSION_DIR => '/temp/';

find( \&wanted, SESSION_DIR );

sub wanted {
    return unless /^cgisess_(.*)/;
    open( FILE, SESSION_DIR . $_ ) or die "Cannot open session $1: $!"
+;
    my $data;
    {
        local $/;
        $data = <FILE>;    
    }
    close( FILE );

    my $D;
    eval( $data );

    if ( time() >= $D->{ _SESSION_ETIME } + $D->{ _SESSION_ATIME } ) {
        unlink( SESSION_DIR . $_ )  or die "Cannot delete session $1: 
+$!";
        print "$1\n";
    }
}
