Why? Examine the full response (headers + content (read html))

Try to login via WWW::Mechanize and after that post message.

I tried but my code is probably wrong. Here is the source of the login page :

<form action="./index.php?page=identify&amp;forum=mxxx&amp;option=iden
+tify" method="post">
                            <table style="width: 90%; margin-left: aut
+o; margin-right: auto;">
                                <tbody><tr>
                                    <td colspan="2">
                                        <div class="titlesection">Pers
+onal Informations</div>
                                    </td>
                                </tr>
                                <tr>

                                    <td>Pseudo</td>
                                    <td><input name="nick" size="20" t
+ype="text"></td>
                                </tr>
                                <tr>
                                    <td>Password</td>
                                    <td><input name="password" size="2
+0" type="password"></td>
                                </tr>
                            </tbody></table>

                            <table style="width: 100%;">
                                <tbody><tr>
                                    <td style="width: 50%; text-align:

                                    <td style="width: 50%; text-align:

                                </tr>
                            </tbody></table>
                            <div class="center"><a href="./index.php?p

My script :

#!/usr/bin/perl -Tw
use diagnostics;
use strict;
use WWW::Mechanize;
use HTTP::Cookies;
my $mech = WWW::Mechanize->new;
my $username = "Username1";
my $password = "Password";
use LWP::Debug qw(+);
$mech->cookie_jar(
        HTTP::Cookies->new(
            file           => "/home/xxx/Documents/Scripts/xxx/Cookie.
+txt",
            autosave       => 1,
            ignore_discard => 1,
        )
    );
my $url = "http://forum.xxx/index.php?page=identify&forum=xxx&option=i
+dentify";
$mech->get($url);
$mech->set_fields( nick => '$username' , password => '$password' ) ;
$mech->click( "Valider");

I don't understand why this field "password" is uncorrect when I look the source-code of tghe login page. I log in the forum and save it with Live HTTP
