Worked on the ktorio/ktor repository to enhance the Compression plugin’s HTTP content negotiation, focusing on compliance with RFC 7231. Developed new logic in Kotlin for Accept-Encoding handling that accurately interprets quality values, excludes encodings with a q value of zero, and prioritizes explicit encodings over wildcards using case-insensitive matching. Refined the backend to ensure the most specific encoding match is selected, while maintaining an uncompressed fallback and existing priority rules. This update improved the reliability of content encoding decisions, reduced encoding-related issues, and strengthened interoperability between clients and servers. Skills applied included API development, backend development, and testing.
