docs: /*
  Look at the request headers and determine if the request is logged in or logged out or if
  it's a support session. Set `req.context.isLoggedIn` and `req.context.isSupportSession` flags
  accordingly. The handler is called very early (immediately after parsing the cookies) and
  all following handlers (including the locale and redirect ones) can rely on the context values.
