Its your basic life cycle of variables aka coping with scoping .... when the program ends, all the variables go away, there are no more variables, that is the life cycle of variables and programs

If you want data to exist past the end of your program , if you want the data to persist, you have to save the data, to a file, to a database... CGI::Session offers a simple API for persisting data with a limited shelf life ...
