Updated!! Oh Anonymous Monk, please accept my apologies for maligning your good, accurate and valuable advice. Yes, this did work when tested properly

Yes, I did try this. The script will compile; however, the data that is persisted in IPC::Lite is not accessible as @url is the RAM @url.

See the following examples

This code will persist the results using IPC::Lite

use IPC::Lite Key => 'TEST', qw(@urls) ;

push( @urls, ("a", "b", "c") );
[download]

This code verifies that the data persists

use IPC::Lite Key => 'TEST', qw(@urls) ;

foreach ( @urls ) {
    print "$_\n";
};

OUTPUT:
a
b
c
[download]

This code uses the method that you referred

require IPC::Lite;
our @urls;
IPC::Lite->import( Key => $0,  qw( @urls ) );

foreach ( @urls ) {
    print "$_\n";
};

OUTPUT:
[download]

There is no output because the variable accessed is the RAM variable

Thanks for the thought
