Form is submit successfully if I copy csrf token from CodeIgniter form
<p>In codeigniter I have enabled csrf protection using <code>$config['csrf_protection'] = TRUE;</code> in config.php file. The token is generate successfully in form and checking in server is it is also working normally. But my question is from inspection using Chrome I am copy whole form and also copy token so form is looks like:</p>

<pre><code>&lt;form action="http://localhost/Dropbox/project/admin/login/ajax_login" method="post"&gt;
    &lt;input type="text" name="email" value="adasd"&gt;
    &lt;input type="password" name="_password"&gt;
    &lt;input type="hidden" name="csrf_test_name" value="cdff17389652a056eee94473661478f3"&gt;
    &lt;input type="submit"&gt;
&lt;/form&gt;
</code></pre>

<p>I am submit this form out of project it is submit successfully 1 time. It is give error on second time. I am copy new token and try again it is working 1 time. It is working 1 time it is normally behaviour or I am missing something on csrf token setting.</p>
