Subject: Upstream: fixed logging level of upstream invalid header errors.
X-Git-Url: http://www.kaiwu.me/postgresql/commit/static/gitweb.js?a=commitdiff_plain;h=dde319ee0c9de26a6f104feb062cfffaa32c16c0;p=nginx.git

Upstream: fixed logging level of upstream invalid header errors.

In b87b7092cedb (nginx 1.21.1), logging level of "upstream sent invalid
header" errors was accidentally changed to "info".  This change restores
the "error" level, which is a proper logging level for upstream-side
errors.
