See this sequence:

User POSTs a form
			Web app processes the form.
			Web app updates its internal state.
			Web app don't output anything, and finishes the POST handling with a  
redirect (implicit GET)

Browser receives the redirect and issues a GET request
			Web app returns content

The important thing is that a POST request *never* returns content, always  
redirects. All content is retrieved using GET.
