julsford has asked for the wisdom of the Perl Monks concerning the following question:

Monks ~ I've hit on one of those wonderful issues that you can only learn when it's too late -- when using LWP::UserAgent to validate the existance of a file before creating a link to it, it will read the entire file into memory. When the files are huge, they are running me out of system memory. I've attempted to set the following:
my $ua = LWP::UserAgent->new(env_proxy =>1, max_size => 100, );
I don't appear to be having any success. Advice would be appreciated.
