Those of you who are familiar with Web applications know that a page is first
requested with a HTTP GET request. If this page contains a form, the form is
normally submitted back to the same address with a POST request. This type of
request is called a postback. Postbacks usually result in redirects to a new
page. But here's the problem. When a Click page is requested, it must construct
its controls before processing the request. But if the request is a postback
that results in a redirect, the controls on the original page are never
rendered, which means they are created for nothing. So my question is this: is
there a way to get around constructing controls during a postback since they
will never be rendered?
