Description
Is your feature request related to a problem? Please describe.
I have a specfic kind of caching logic that should not use the header values. In the current implementation of the CacheKeyGenerator there is a static list of key generators that I cannot modify.
Describe the solution you'd like
Add an api or spring mechanism to change the key generator.
Describe alternatives you've considered
I tried to modify that static field at runtime but this approach is really hacky.
Additional context
I have not used spring for a long time. Maybe there is already a way to change the CacheKeyGenerator or ResponseCache implementation.

Research direction
Start by reading ResponseCacheGatewayFilter, CacheKeyGenerator, and the ResponseCache implementation to map the current static key-generator path and how header values affect cache keys. Define a supported Spring customization point that avoids runtime mutation of the static field, then verify that custom key-generation and existing caching behavior work as intended.
