Worked on the OpenRailAssociation/osrd project to enhance HTTP proxy reliability by addressing response streaming compliance for empty-body status codes. Focused on backend development using Rust, the work involved implementing conditional logic in the API gateway to prevent unnecessary data transfer for HTTP responses with 1xx, 204, and 304 status codes. By aligning the proxy’s behavior with HTTP protocol semantics, the solution improved client compatibility and bandwidth efficiency. The approach ensured that response bodies were only streamed when appropriate, reducing overhead and strengthening the proxy layer’s adherence to protocol standards. This contribution centered on bug resolution rather than feature development.
