cgi input file size	Can't Post

i'm writing a code to upload my files to a webserver so i have cgi code and a file input type in html how can i get the entry file size ?

i searched about it and i got that it's possible to use the $ENV{CONTENT_LENGTH} variable to get the file size but it seems that it first get the whole content and then return the size but my goal is to get the file size before fetching it.

thanks

you can try to use HEAD request, and extract content length:

use strict;
use warnings;

use LWP::UserAgent;
use Data::Dumper;

my $browser = LWP::UserAgent->new;
my $response = $browser->head('http://mirrors.kernel.org/gnu/git/gnuit-4.9.3.tar.gz');
$response->content_length;
