The Problem is:

I can access a web page "http://eonet.level3.com" using IE, but when i try to access the same page using WWW::Mechanzie or LWP::UserAgent i am getting "401 Unauthorized" error.

I have given below the code is used and the output i got

The Code:

#!C:/Perl/bin/perl.exe
use LWP::Simple;
use LWP::UserAgent;
use HTTP::Request;
use HTTP::Response;
use HTML::LinkExtor;
my $URL= "http://eonet.level3.com/";
$browser = LWP::UserAgent->new();
$browser->timeout(10);
my $request = HTTP::Request->new(GET => $URL);
my $response = $browser->request($request);
if ($response->is_error()) {printf "%s\n", $response->status_line;}
$contents = $response->content();
#print $contents;
print $response->status_line(), "\n";
print $response->headers()->as_string();


Output when i run the program:

C:\Documents and Settings\g.venkatesan\Desktop>perl lwp_test.pl
