 While the principal may be passed to the services layer to enable it to make the authorization decision, doing so would introduce an additional argument on every services layer method.
 A more elegant approach is to use a `ThreadLocal` to hold the principal, although this would likely increase development time to a point where it would become more economical (on a cost-benefit basis) to use a dedicated security framework.

 Writing your own authorization code from scratch does not provide the "`design check`" a framework would offer, and in-house authorization code typically lacks the improvements that emerge from widespread deployment, peer review, and new versions.

 Verify this by checking whether the browser is actually sending the request (check your server access logs and the debug log or use a suitable browser debugging plugin, such as "`Tamper Data`" for Firefox). This has nothing to do with Spring Security, and you should configure your application or server to set the appropriate `Cache-Control` response headers.

 === Why does the session ID change when I authenticate through Spring Security?
 
 With the default configuration, Spring Security changes the session ID when the user authenticates.
-If you us a Servlet 3.1 or newer container, the session ID is simply changed.
+If you use a Servlet 3.1 or newer container, the session ID is simply changed.
 If you use an older container, Spring Security invalidates the existing session, creates a new session, and transfers the session data to the new session.
 Changing the session identifier in this manner prevents "`session-fixation`" attacks.
 You can find more about this online and in the reference manual.

 This happens because sessions created under HTTPS, for which the session cookie is marked as "`secure`", cannot subsequently be used under HTTP. The browser does not send the cookie back to the server, and any session state (including the security context information) is lost. Starting a session in HTTP first should work, as the session cookie is not marked as secure.
