Subject: [PATCH 02/38] www: gzip_filter: implicitly flush {obuf} on zmore/zflush
Date: Sat, 10 Sep 2022 08:16:53 +0000	[thread overview]
Message-ID: <20220910081729.2011934-3-e@80x24.org> (raw)
In-Reply-To: <20220910081729.2011934-1-e@80x24.org>

This seems like the least disruptive way to allow more use of
->zmore when streaming large messages to sockets.
