Subdomain Routing

The worker uses a SUBDOMAIN_ORIGINS map to route requests based on the Host header.

Extraction

Section titled “Extraction”
function extractSubdomain(hostname) {
  const match = hostname.match(/^(.+)\.cubecommons\.org$/);
  if (!match || match[1] === 'www') return null;
  return match[1];
}

Multi-level subdomains are supported: sustainability-transparency.cubecommons.org extracts as sustainability.transparency.

Apex Redirect

Section titled “Apex Redirect”

Requests to bare cubecommons.org redirect to either:

  • home.cubecommons.org if the user has a valid cc_access cookie
  • token.cubecommons.org if not authenticated

Cross-Subdomain Auth

Section titled “Cross-Subdomain Auth”

Cookies are set with Domain=.cubecommons.org so they work across all subdomains. The cc_access cookie carries the token, and cc_sid carries the TOTP session.
