Lighttpd

Hi, nginx <http://nginx.net/> provides the ability to specify how much of the request/response is buffered in memory and request/responses larger than that are buffered on filesystems
This would be useful for large POST requests (file-uploads) from slow clients or slow backends becayse lighty would manage the client handling and the backend would slurp the large request from the relatively quick connection between it and lighty

When you configure nginx, it defaults to providing the following parameters

nginx http client request body temporary files: $prefix/client_body_temp
nginx http proxy temporary files: $prefix/proxy_temp
