WININET_E_HEADER_NOT_FOUND
WININET_E_HEADER_NOT_FOUND is a WinINet HRESULT. It means that the request or response does not contain the header queried by the application. It is often returned while using HttpQueryInfo to obtain an optional HTTP header or to enumerate repeated headers.
What to check
- Confirm that the code queries the expected request or response handle after the headers have been received.
- Treat absent optional headers as a normal condition instead of assuming every response has the same metadata.
- When enumerating repeated headers, stop cleanly when no further index exists.
