描述

Ideally I'd like to first receive the request body and use that to generate the CacheKey. Is this currently possible without forking Pingora? I wonder if it fits in the current lifecycle management.

研究方向
First, examine the Pingora source code, particularly the `CacheKey` generation in the `Cache` trait and the request handler lifecycle hooks to determine if the request body is available before cache key generation. Review any existing tests or documentation related to cache key customization. Then, discuss in the issue whether a new hook or method could be added to allow body based cache keys, referencing similar patterns in other caching proxies. Finally, propose a minimal design for maintainer feedback.
