Window Sizing for Zstandard Content Encoding
RFC 9659, “Window Sizing for Zstandard Content Encoding”, is an Informational document published in September 2024 by N. Jaju, W. F. Handte. It updates RFC 8878. The canonical text is published by the RFC Editor.
Abstract
Deployments of Zstandard, or "zstd", can use different window sizes to limit memory usage during compression and decompression. Some browsers and user agents limit window sizes to mitigate memory usage concerns, thereby causing interoperability issues. This document updates the window size limit in RFC 8878 from a recommendation to a requirement in HTTP contexts.
