Subject: Proxy: $proxy_internal_body_length fixed.
X-Git-Url: http://www.kaiwu.me/postgresql/commit/?a=commitdiff_plain;h=307b61771284a76d431e253dfcc9c1f7ec73e94c;p=nginx.git

Proxy: $proxy_internal_body_length fixed.

The $proxy_internal_body_length value might change during request lifetime,
notably if proxy_set_body used, and use of a cached value might result in
incorrect upstream requests.

Patch by Lanshun Zhou.
