Correction of the tracker domain allowlist logic to handle case-insensitive hostnames correctly.
Raw Developer Origin & Technical Request
GitHub Issue
Jul 30, 2026
## Source-confirmed behavior
I reviewed the tracker at exact base
`8248ccf3333b9d490712b53a87806abb2e2541cf`.
`data-domain` and `data-cross-domain-domains` are normalized to lowercase, but
the ordinary `data-domains` allowlist is only trimmed:
github.com/talivia-group/tal...
That value is later compared directly with `location.hostname`:
github.com/talivia-group/tal...
A source-equivalent reproduction gives:
- browser URL `WWW.Example.COM/` → hostname `www.example.com`
- allowlist entry `Example.COM` → no match
- allowlist entry `example.com` → match
Since hostnames are case-insensitive, mixed-case configuration currently
silently prevents the tracker from sending analytics. I did not inspect any
customer data or authenticated Talivia Cloud surface.
## Optional focused patch — $30 fixed
I can implement and test the smallest tracker-only correction:
- normalize each non-empty `data-domains` entry after trimming;
- cover mixed-case exact-host and subdomain matches;
- prove a genuinely different hostname remains blocked;
- preserve DNT, explicit disable, cookie-domain, cross-domain, and all other
tracker behavior;
- run the focused tracker tests, lint, and tracker build.
### Acceptance criteria
- `data-domains="LOCALHOST"` behaves exactly like
`data-domains="localhost"`.
- Mixed-case par...
