So, i tried out downloading the files in various ways from these links:
CPAN: http://search.cpan.org/CPAN/authors/id/H/HM/HMBRAND/Text-CSV_XS-1.01.tgz
BackPAN: http://backpan.perl.org/authors/id/H/HM/HMBRAND/Text-CSV_XS-1.01.tgz
Notably different browsers and sources resulted not only in different sizes, but also different filenames. The platform used for all cases is Windows 7. The results are as follows:
Browser |
CPAN Name |
CPAN Size |
BPAN Name |
