+### Proxy max temp file size
+
+When [`buffering`](http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_buffering) of responses from the proxied server is enabled, and the whole response does not fit into the buffers set by the [`proxy_buffer_size`](http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_buffer_size) and [`proxy_buffers`](http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_buffers) directives, a part of the response can be saved to a temporary file. This directive sets the maximum `size` of the temporary file setting the [`proxy_max_temp_file_size`](http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_max_temp_file_size). The size of data written to the temporary file at a time is set by the [`proxy_temp_file_write_size`](http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_temp_file_write_size) directive.
+
+The zero value disables buffering of responses to temporary files.
+
+To use custom values in an Ingress rule, define this annotation:
+```yaml
+nginx.ingress.kubernetes.io/proxy-max-temp-file-size: "1024m"
+```

 ### Proxy HTTP version
 
 Using this annotation sets the [`proxy_http_version`](http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_http_version) that the Nginx reverse proxy will use to communicate with the backend.
