- [nitpick] Consider renaming the option constructor 'Match' to something more descriptive (e.g., 'WithCacheRule') to clearly differentiate it from the Rule.Match method.

[nitpick] Add a comment clarifying that only the first matching rule is applied to help future maintainers understand the middleware behavior when multiple rules might match.

Hey @cnlangzi - I've reviewed your changes - here's some feedback:
- Consider if case-insensitive path matching (
EqualFold) is the desired behavior for cache rules.
Here's what I looked at during the review
- 🟢 General issues: all looks good
- 🟢 Security: all looks good
- 🟢 Testing: all looks good
- 🟢 Documentation: all looks good
