in reply to Living on the edge

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 BPAN Size
wget Text-CSV_XS-1.01.tgz 123288 Text-CSV_XS-1.01.tgz 123288
Internet Explorer 10 Text-CSV_XS-1.01.gz 123298 (+10) Text-CSV_XS-1.01.tar 123288
Opera 12 Text-CSV_XS-1.01.tgz 123288 Text-CSV_XS-1.01.tgz 123288
Firefox 24 Text-CSV_XS-1.01.tgz 123298 (+10) Text-CSV_XS-1.01.tgz 123288
