| Filtering System | Blocking Mechanism | Google Sites Proxy Evasion? | Reason | | :--- | :--- | :--- | :--- | | DNS Blacklist | Domain denylist | | The requested domain is sites.google.com (allowlisted). | | SNI Inspection | TLS Server Name Indication | Yes | The SNI reveals sites.google.com , not the target. | | URL Keyword Filter | Regex on path (e.g., proxy.php ) | Yes | Path is /a/.../edit or similar; no proxy signatures. | | DPI Pattern Matching | Static proxy headers | Partial | If the relay script uses known CORS proxies (e.g., cors-anywhere ), DPI can block the outbound fetch, but not the Sites page itself. | | Content Security Policy | frame-ancestors / connect-src | No | A strict CSP blocking connect-src * would break the proxy. | google sites proxy unblocker
