title: Valid use case for @PostAuthorize And @PostFilter annotations
body: <p>We have just migrated to Spring Security <strong>3.0.8</strong> from <strong>2.0.8</strong> (Can' upgrade to the latestversion which is <strong>3.2.X</strong> as our <strong>core spring libraries</strong> are still on <strong>3.0.X</strong>, which we plan to upgrade later when business permits).</p>
  
  <p>I understand that we now have annotations for securing methods like <code>@PreAuthorize</code>, <code>@PostAuthorize</code>, <code>@Secured</code>, <code>@PreFilter</code> and <code>@PostFilter</code>.</p>
  
  <p>I understand the use of <code>@PreAuthorize</code>, which really makes sense. But can't think of any valid use cases where you would ever use <code>@PostAuthorize</code> or <code>@PostFilter</code> annotation? </p>
  
  <p>Can somebody who used it please explain to me a reasonable use-case for using them?</p>
  
  <p>Thanks in advance!</p>
