During July 2025, Max Meyer focused on improving the reliability of WebSocket upgrade handling in the zalando/skipper repository. He addressed a bug where WebSocket upgrade requests failed due to case sensitivity in the Connection header by updating the Go backend code to perform case-insensitive header value lookups. This change enhanced interoperability with a broader range of clients. Max also implemented a regression test to ensure future stability in header matching. His work demonstrated a strong understanding of HTTP protocol nuances and backend networking, delivering a targeted, well-tested fix that improved the robustness of Skipper’s WebSocket support without introducing new features.
