From: Piotr Sikora Date: Wed, 1 Oct 2014 22:48:53 +0000 (-0700) Subject: Upstream: fix $upstream_cache_last_modified variable. X-Git-Tag: release-1.7.7~19 X-Git-Url: http://git.kaiwu.me/postgresql/log/contrib/postgres_fdw/postgres_fdw.c?a=commitdiff_plain;h=4a2fba2d46d8d315a3dd3792d9f9c2d13e17a794;p=nginx.git Upstream: fix $upstream_cache_last_modified variable. Due to the u->headers_in.last_modified_time not being correctly initialized, this variable was evaluated to "Thu, 01 Jan 1970 00:00:00 GMT" for responses cached without the "Last-Modified" header which resulted in subsequent proxy requests being sent with "If-Modified-Since: Thu, 01 Jan 1970 00:00:00 GMT" header.
