i search for this http://curl.haxx.se/mail/lib-2002-04/0223.html
on CPAN pure documentation, working examples but there are no fully help about all params
hmmm, now i have a problem like this Undefined subroutine &Curl::easy::getinfo called at p.pl line 62
Line 62: $start = $curl->$getinfo(CURLINFO_STARTTRANSFER_TIME);
but $bytes = $curl->getinfo(CURLINFO_SIZE_DOWNLOAD); works fine
