To get the HTTP response headers such as content length from a web server

I would like to use Perl to help me download some files by using the
curl command like this

system("curl https://www.foo.com/ -o ~/sample/Test.exe");

I need to fasten this process by simultaneously running three threads
that run the same curl command but different parts of the file. Hence
speeding up the process.

But for this I need to find the size of the file that needs to be
downloaded I thought that by getting the HTTP response for the
particular GET request I shall get the file size.

Can somebody help me how to go about with this........

use the LWP::Simple module:

perl -MLWP::Simple '(undef, $len) = head "http://www.foo.com"; print $len'

You can download them with native Perl, no need for curl...
