Reverse Proxy that does not buffer uploads

Question

From what I've seen of various reverse proxies (nginx, apache, varnish), they seem to buffer file uploads to disk before handing them off to the service they're proxying for. I need a reverse proxy that doesn't do this; I have a system that handles uploads itself, and buffering uploaded files to disk is not something that works for me. Does anybody know of a proxy server that can be configured to just pass traffic through to the proxied services without doing any buffering to disk?

You can disable Nginx file buffering by setting proxy_max_temp_file_size to 0. The documentation on this directive says as much:

The zero value disables buffering of responses to temporary files.

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

I didn't think that Apache ProxyPassReverse did any buffering to disk. Doing some quick reading, it looks like you have to use mod_disk_cache to enable using the disk - so out of the box, I don't think that it will do what you think it's doing.

Ok, I must have mis-remembered that. Thanks for the info! – tsuraan Jan 06 '11 at 22:34
Neither HAProxy nornginx do any disk buffering for proxying, unless you configure it to do so explicitly (only possible with nginx). – Holger Just Apr 18 '11 at 10:05
