Subject: Proxy: fix keepalive for HTTP/2 with explicit or no body
X-Git-Url: http://www.kaiwu.me/postgresql/commit/static/gitweb.js?a=commitdiff_plain;h=1a2adac356e57893fad82f0637fb12b27d581242;p=nginx.git

Proxy: fix keepalive for HTTP/2 with explicit or no body

Previously, when an HTTP/2 request had no body or an explicit body
was set by proxy_set_body, the request consisted of only one buffer,
which had no b->last_buf flag set.  This prevented ctx->output_closed
from being set after processing this buffer.  Consequently,
u->keepalive might not be set to store the connection in the
keepalive cache.
