Feb 1, 2026February 2026 monthly summary for navikt/testnorge: Delivered an Authentication Token Caching feature for the dolly-proxy service. Implemented a TokenCache to store tokens for a defined duration, reducing redundant token exchanges and lowering latency in authentication flows. The change improves overall responsiveness by minimizing calls to external token services and establishes a foundation for additional caching strategies. Commit 13ed2422c09baacfb00196aec56c0f5f4c5e76c4: "feature/dolly-proxy-token-caching (#4127) Added new TokenCache, for tokens except Fakedings."
