Combine partial content only with a compatible representation.
- A server can ignore Range and return the complete representation.
- 206 Partial Content describes selected ranges; 416 signals an unsatisfiable range request.
- If-Range lets a client request a range only while its validator remains valid, otherwise receiving the full representation.
Content-Range describes the returned interval. Multipart responses can carry several ranges. Range requests are optional and need resource-use safeguards.
