- Added functionality to mark responses as cache hits to prevent incorrect X-Cache headers.
- Introduced setCacheHitFlag function to traverse response writer wrappers and set cache hit flag.
- Updated cachingResponseWriter to manage cache hit state and adjust X-Cache header accordingly.
- Enhanced ProcessRequest and ProcessResponse methods to utilize new caching logic.
feat(extension): Introduce ResponseWriterWrapper and ResponseFinalizer interfaces
- Added ResponseWriterWrapper interface for extensions to wrap response writers.
- Introduced ResponseFinalizer interface for finalizing responses after processing.
refactor(manager): Improve response writer wrapping and finalization
- Updated Manager.Handler to wrap response writers through all enabled extensions.
- Implemented finalization of response writers after processing requests.
test(caching): Add comprehensive integration tests for caching behavior
- Created caching_test.go with tests for cache hit/miss, TTL expiration, pattern-based caching, and more.
- Ensured that caching logic works correctly for various scenarios including query strings and error responses.
test(routing): Add integration tests for routing behavior
- Created routing_test.go with tests for route priority, case sensitivity, default routes, and return directives.
- Verified that routing behaves as expected with multiple regex routes and named groups.
- Introduced IgnoreRequestPath option in proxy configuration to allow exact match routing.
- Implemented proxy_pass directive in routing extension to handle backend requests.
- Enhanced error handling for backend unavailability and timeouts.
- Added integration tests for reverse proxy, including basic requests, exact match routes, regex routes, header forwarding, and query string preservation.
- Created helper functions for setting up test servers and backends, along with assertion utilities for response validation.
- Updated server initialization to support extension management and middleware chaining.
- Improved logging for debugging purposes during request handling.
