May 1, 2025May 2025 — Apache Causeway: Implemented PDF Viewer NoCache flag and explicit zero-cache handling to ensure fresh PDF rendering. Added timestamp-based cache busting to document URLs and refactored ResourceStreamRequestHandler to enforce zero cache duration. This improves data freshness, reduces stale content, and aligns with dynamic content policies. Work linked to CAUSEWAY-3891 commit (5fbcdd60daba351d3177fa1f3427f4e4b9b9d547).
