Http Qlcd3utezilsips2onion Patched

The 16-character string "qlcd3utezilsips2.onion" refers to a legacy v2 onion address that was decommissioned in October 2021 following the Tor Project's transition to more secure v3 addresses. These older services were retired due to security vulnerabilities, rendering this specific link inactive on current Tor browsers.

7. Security Considerations

• Do not log original .onion responses unless in debug mode
• Rate-limit patched requests to avoid DoS of hidden service
• Sanitize patch values — prevent header injection via newlines
• Optional: hash validation of original vs patched request to detect tampering by Tor exit (though exit is not used for .onion)
