laravel's Session flush and forget methods not working as expected
<p>I tried to delete a value from my session using :</p>

<pre><code>Session::forget('value')
</code></pre>

<p>but it didn't delete!</p>

<p>However,  when i tried using <code>save</code> method like so :</p>

<pre><code> Session::forget('value')
 Session::save()
</code></pre>

<p>it worked!  (I.e. the value was deleted from the session.)</p>

<p>Please - what am I doing wrong?  I don't see the <code>save</code> method in the Laravel documentation when using <code>Session::flush()</code> and <code>Session::forget()</code>.</p>
