Fwd: New Version Notification for draft-jaju-httpbis-zstd-window-size-00.txt

Hi all,

I wrote a draft regarding window sizes in Zstandard Content Encoding that
aims to update RFC8878 <https://datatracker.ietf.org/doc/html/rfc8878> to
require a specific limit for improved interoperability.

For context, we recently shipped zstd Content Encoding support in Chrome
123 and came across incompatibilities in the field where developers were
confused when their compressed content was not able to be decoded by
Chrome, but was correctly decoded by curl and the zstd CLI. Having an
explicit agreed-upon limit would help deployers of zstd to align their
implementations and cause less user friction.

I believe this topic was also previously discussed at
https://lists.w3.org/Archives/Public/ietf-http-wg/2021JulSep/0137.html and
https://lists.w3.org/Archives/Public/ietf-http-wg/2023JulSep/0178.html.
This was also discussed at the W3C WebPerf WG meeting
<https://docs.google.com/document/d/1ijP7yc6UXZVgzpXDVmBa7h70gxLpFcqdlOZzL3DRT_0/edit#heading=h.xn2d3li0b8op>
at TPAC 2023.

Please let us know what you think.

Best regards,
Nidhi

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, causing interoperability issues.  This document updates the
   window size limit in RFC8878 from a recommendation to a requirement
   in HTTP contexts.
