When viewing the [url=http://wiki.nginx.org/NginxHttpCoreModule#client_body_in_file_only]documentation for client_body_in_file_only[/url], it shows the only possible values as [b]on/off[/b].
My confusion occurs when viewing the PHP-FPM [url=http://php-fpm.org/wiki/Features#Accelerated_upload_support]suggested usage of client_body_in_file_only[/url], as it shows the directive with a value of [b]clean[/b].
This makes me wonder if there is possibly an undocumented feature of Nginx client_body_in_file_only, to clean/remove the resulting file at some point?
Or is PHP-FPM's documentation just incorrect?
Thanks!
