These reports appear to relate to SSL upstream connections (both refer
to ngx_http_upstream_check_broken_connection). I'm talking about an SSL
client connection, with a plain http upstream connection.
When an https client drops it's connection, the upstream http proxy
connection is not dropped. If nginx can't detect an https client
disconnect properly, that must mean it's leaking connection information
internally doesn't it?
