2790 * There can be no USER_INT objects on the page ("isINTincScript()" / "isEXTincScript()") because they implicitly indicate dynamic content
2791 * There can be no logged in user because user sessions are based on a cookie and thereby does not offer client caching a chance to know if the user is logged in. Actually, there will be a reverse problem here; If a page will somehow change when a user is logged in he may not see it correctly if the non-login version sent a cache-header! So do NOT use cache headers in page sections where user logins change the page content. (unless using such as realurl to apply a prefix in case of login sections)
