Why isn't a GraphQL response as cacheable at the HTTP layer as a REST GET?
Short interview answer
Most GraphQL traffic goes over POST to a single endpoint with a query body, so URL-based HTTP and CDN caching doesn't apply directly; caching typically requires a dedicated layer such as persisted queries or a normalized client cache.
Key takeaway
Explain the underlying mental model clearly, then support it with a concrete example and its trade-offs.
