"uwsgi_cache_path"

       Thanks to Damien Tournoud.

       while proxying.

    *) Bugfix: the "proxy_pass", "fastcgi_pass", \

Changes with nginx 1.7.8                                         02 Dec 2014

    *) Change: now the "If-Modified-Since", "If-Range", etc. \ 
client request
       header lines are passed to a backend while caching if nginx knows in
       advance that the response will not be cached (e.g., when using
       proxy_cache_min_uses).

    *) Change: now after proxy_cache_lock_timeout nginx sends a request to a
       backend with caching disabled; the new directives
       "proxy_cache_lock_age", "fastcgi_cache_lock_age",
       "scgi_cache_lock_age", and "uwsgi_cache_lock_age" \ 
specify a time
       after which the lock will be released and another attempt to cache a
       response will be made.

    *) Change: the "log_format" directive can now be used only at http
       level.

    *) Feature: the "proxy_ssl_certificate", \ 
"proxy_ssl_certificate_key",
       "proxy_ssl_password_file", "uwsgi_ssl_certificate",

       "X-Accel-Redirect".
       Thanks to Toshikuni Fukaya.

connections.

    *) Feature: new directives in vim syntax highliting scripts.
       Thanks to Peter Wu.

"Cache-Control"
       backend response header line.
       Thanks to Piotr Sikora.

    *) Bugfix: in the ngx_http_spdy_module.
       Thanks to Piotr Sikora.

       0.9.8zc, 1.0.0o, 1.0.1j.

    *) Bugfix: alerts "header already sent" appeared in logs if the
       "post_action" directive was used; the bug had appeared in 1.5.4.

    *) Bugfix: alerts "the http output chain is empty" might appear in logs
       if the "postpone_output 0" directive was used with SSI includes.

    *) Bugfix: in the "proxy_cache_lock" directive with SSI subrequests.
       Thanks to Yichun Zhang.

       backend response while caching.

    *) Feature: the "proxy_force_ranges", "fastcgi_force_ranges",
       "scgi_force_ranges", and "uwsgi_force_ranges" directives.

    *) Feature: the "proxy_limit_rate", "fastcgi_limit_rate",
       "scgi_limit_rate", and "uwsgi_limit_rate" directives.

    *) Feature: the "Vary" parameter of the \ 
"proxy_ignore_headers",
       "fastcgi_ignore_headers", "scgi_ignore_headers", and
       "uwsgi_ignore_headers" directives.

    *) Bugfix: the last part of a response received from a backend with
       unbufferred proxy might not be sent to a client if "gzip" or \ 
"gunzip"
       directives were used.

    *) Bugfix: in the "proxy_cache_revalidate" directive.
       Thanks to Piotr Sikora.

    *) Bugfix: in error handling.
       Thanks to Yichun Zhang and Daniil Bondarev.

    *) Bugfix: in the "proxy_next_upstream_tries" and

    *) Security: it was possible to reuse SSL sessions in unrelated contexts
       if a shared SSL session cache or the same TLS session ticket key was
       used for multiple "server" blocks (CVE-2014-3616).
       Thanks to Antoine Delignat-Lavaud.

    *) Change: now the "stub_status" directive does not require a \

       "set" directive was used to change the "$http_...", \ 
"$sent_http_...",
       or "$upstream_http_..." variables.

    *) Bugfix: in memory allocation error handling.
