Subject: [PATCH 36/43] wwwstream: eliminate ::response, use html_oneshot
Date: Sun,  5 Jul 2020 23:27:52 +0000	[thread overview]
Message-ID: <20200705232759.3161-37-e@yhbt.net> (raw)
In-Reply-To: <20200705232759.3161-1-e@yhbt.net>

All of our streaming responses use ::aresponse, now, and our
synchronous responses use html_oneshot.  So there's no need
for the old WwwStream::response.
