When would I use Server.Transfer over PostBackURL?
<p>Or vice versa.</p>

<p>Update:<br />
Hmm, let's assume I have a shopping cart app, the user clicks on the Checkout button.
The next thing I want to do is send the user to a Invoice.aspx page (or similar). When the user hits checkout, I could  Button.PostBackURL = "Invoice.aspx" <br />
or I could do<br />
<code> Server.Transfer("Invoice.aspx") </code>  </p>

<p>(I also changed the title since the method is called Transfer and not TransferURL)</p>
