Well, find out what the browser sends. Match what the browser sends.

For one thing, the browser wouldn't be sending an invalid url. (Note the space.)

This is the third time you've posted this (first in your previous thread then again anonymously Reaped: Mechanize Help). Please remember to login and don't post the same question multiple times. You don't need to start a new thread when one already exists for the same problem.

I am new to perlmonk and I didn't realize that I got logged out. Also I was unable to track my previous post. So accidentally I made anonymous post. Even anonymous post post was not visible to me and then I realized that I have been logged out. So Again I logged in and posted my question. Sorry for accidentally spamming.

Welcome to the Monastery. A few things. When posting without logging in you actually get prompted to do so at after the 'preview' stage:

You aren't logged in.

Login, Create a new user, or hit "Create" to proceed in posting your node.

It's pretty hard to miss. If you aren't logged in you don't get to see posts which are yet to be approved. Once logged in you receive a message when someone replies to your post. Perhaps you should spend some time familiarising yourself with the monastery. See Understanding and Using PerlMonks from the tutorials section of the site.

#!usr/bin/perl 

use strict;
use warnings;
use LWP::UserAgent;

my $ua = LWP::UserAgent->new;
$ua->timeout(2);
$ua->env_proxy;
my $response = $ua->get('http://www.justdial.com');
#open(STDOUT, '>', 'just_dial.html');
if ($response->is_success) {
    print $response->decoded_content;
}
else {
    die $response->status_line;
}

For saving content, there also is the convenient ->save_content method. This also saves you the binmode call on STDOUT if you're trying to save binary data.

Why did you post three requests? Why are none of them are for the url you say you want to fetch?
