Subject: Upstream: skip empty cache headers.
X-Git-Tag: release-1.5.8~29
X-Git-Url: http://git.kaiwu.me/postgresql/log/contrib/postgres_fdw/static/gitweb.js?a=commitdiff_plain;h=3dec2b131cd1787d0022fa6b7d8e7c8997c0a862;p=nginx.git

Upstream: skip empty cache headers.

Notably this fixes HTTP_IF_MODIFIED_SINCE which was always sent with
cache enabled in fastcgi/scgi/uwsgi after 43ccaf8e8728.
