there are several different ways to do this.

1: If it is discrete pieces of data like names, addresses or whatever, you can use a "sqlite" database. No engine needed, just the libraries and one database file. You'll need to know SQL of course.

2: If you're worried about leaving a mess, keep a variable with a list of the file names in it, like $TMPFILES, then at the end, just rm $TMPFILES. Another thing you can do is use $$ to create them. e.g. TMP1=/tmp/$$.tmp

You can use variables if you're not dealing with tons and tons of data.

CGI::Session::Driver::sqlite(3) 			User Contributed Perl Documentation			   CGI::Session::Driver::sqlite(3)

CGI::Session::Driver::sqlite - CGI::Session driver for SQLite SYNOPSIS
$s = new CGI::Session("driver:sqlite", $sid, {DataSource=>'/my/folder/sessions.sqlt'}); $s = new CGI::Session("driver:sqlite", $sid, {Handle=>$dbh}); or $s = new CGI::Session('driver:sqlite', undef, { TableName=>'session', IdColName=>'my_id', DataColName=>'my_data', Handle=>$dbh, }); DESCRIPTION
sqlite driver stores session data in SQLite files using DBD::SQLite DBI driver. More details see CGI::Session::Driver::DBI, its parent class. DRIVER ARGUMENTS
Supported driver arguments are DataSource and Handle. At most only one of these arguments can be set while creating session object. DataSource should be in the form of "dbi:SQLite:dbname=/path/to/db.sqlt". If "dbi:SQLite:" is missing it will be prepended for you. If Handle is present it should be database handle ($dbh) returned by DBI::connect(). As of version 1.7 of this driver, the third argument is NOT optional. Using a default database in the temporary directory is a security risk since anyone on the machine can create and/or read your session data. If you understand these risks and still want the old behavior, you can set the "DataSource" option to '/tmp/sessions.sqlt'. BUGS AND LIMITATIONS
None known. LICENSING
For support and licensing see CGI::Session perl v5.16.3 2008-07-16 CGI::Session::Driver::sqlite(3)
