969	proxy module does not honour proxy_max_temp_file_size on cacheable responses	Stealthii@…		"In the ngx_http_proxy module, there is a directive: `proxy_max_temp_file_size` - it is intended to limit the size of buffered files on disk. There is a caveat:

 > ""This restriction does not apply to responses that will be cached or stored on disk.""

http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_max_temp_file_size

Why is this the case? I have an issue when using the slice module - I'm proxying a large request, and Nginx sends smaller range requests to the proxied server, for ~16MB hunks of the resource. Sometimes the proxied server misbehaves, and responds with a ranged response from the offset, till the end of the very large file.

Nginx will continue to 'temporarily' buffer this file to disk, resulting in a blocked downstream request, and an ever increasing use of the temporary proxy storage. The upstream file is multiple terabytes - Nginx should honor this directive and terminate the upstream range response when it receives over the max size for buffered files."	enhancement	new	minor		nginx-module	1.9.x		slice proxy cache temp		Linux 1dcda8eab5c1 4.4.8-boot2docker #1 SMP Mon Apr 25 21:57:27 UTC 2016 x86_64 Linux	"nginx version: nginx/1.9.15
