ASP.NET Form Authenticaion
<p>I have created ASP.NET project and connect it to database. After I just added Login and Register control. Something like:</p>

<pre><code>    &lt;asp:Login ID="Login1" runat="server" 
        DestinationPageUrl="~/Users/UserAccount.aspx"&gt;
    &lt;/asp:Login&gt;
</code></pre>

<p>Actually it works! It does registration and login operation. But HOW? Where is a code, where is SQL statement? I don't see anything related to that. Could you please explain me how it works? and how do I modify say registration control if I need extra information.</p>

<p>Thanks!</p>
