After my first Node (DON'T) use Data::Dumper to implement Object persistence (the next above)
I understand that my first Idea is not so cool ... :-)
That there are a lot of way to make a lightweight object persistence, and Data::Dumper is the more stupid
In this version I use DBM::Deep to make the work, seems that with Data::Dumper and the eval function I have a big security hole in code
(a bad boy can substitute one object file with somethins like system ("rm -rf /") and destroy my server).
So I try to implement an Object Persistence with a db file and the class DBM::Deep.


Dump the Object
my $db = new DBM::Deep "$dumpfile" or die "Can't open Dump FILE!";
$db -> import ($probeset);

[download]

Where $probeset is a reference to an Object.


Import the Object
In another CGI script... 
my $db = new DBM::Deep "$dumpfile";
my $struct = $db -> export();

[download]
And now bless the Object with the specific Class!
my $class = 'Probeset';
my $probeset = bless $struct, $class;

[download]

Hope that could be useful. Regards.

There is nothing which cannot be answered by means of my doctrine," said a monk, coming into a teahouse where Nasrudin sat. "And yet just a short time ago, I was challenged by a scholar with an unanswerable question," said Nasrudin. "I could have answered it if I had been there." "Very well. He asked, 'Why are you breaking into my house in the middle of the night?'"
