Understanding the Private Laboratory Access Gate

The private laboratory access gate runs before normal Joomla loading where supported, so an unauthenticated visitor should not be able to browse the cloned site or static assets.

How the gate works

• QCUL generates qc-update-lab-gate.php for the run.
• Apache/LiteSpeed rewrite rules route unauthenticated requests through the gate.
• The run-specific access code establishes an HttpOnly, SameSite=Strict cookie scoped to the laboratory path.
• QCUL applies X-Robots-Tag/no-store protections and robots controls in addition to authentication.

Gate verification

Before declaring the laboratory ready, QCUL loopback-tests blocked unauthenticated access, static-file protection, credential acceptance, cookie issuance, and authorized Joomla loading. A failed gate check is a creation problem, not a warning you should ignore.

If rewrite is unavailable

QCUL treats the absence of a safe external gate as a serious boundary. Do not make the private copy publicly accessible just to continue testing; correct the web-server/rewrite environment or use another safe test approach.

Safety check before update testing

Before relying on Understanding the Private Laboratory Access Gate, confirm the private copy still shows laboratory identity, its access gate works, and ordinary browsing stays inside the lab rather than silently using production. The cloned site contains production-derived data, so a laboratory that is not demonstrably isolated should be repaired or refreshed before any update rehearsal.
