Representation identity ignores one of the selected request headers · case 02

Representation identity ignores one of the selected request headers.

Member previewVariant 2 · 3 implementations · 4 checks per implementation

Case contract

Header names are already normalized lowercase and values are strings. Return sorted unique requested Vary names paired with value or None for missing fields; ignore unselected headers.

Why this case matters

A deterministic cache state transformation. Inputs are copied or treated as immutable; no remote storage, real clock, or concurrent interleaving is simulated.

One recorded failure
