Not nginx related but have you thought about redesigning the architecture so that the connection basically queues the request, then the browser is told to refresh every so often and it will check the status until it is completed?

Seems more scalable than an app that relies on the web connection staying open for 30-60+ minutes

Hi,

I'm running nginx 0.7.24 along with Mongrel. On an admin, non public facing site, I have tasks that involve lots of computation and can take up to 15-30 minutes to run.

I've configured nginx to wait a long while for a response from Mongrel, but what happens is that Mongrel will complete the task, but nothing is returned to the browser. It just sits there as if the operation is still running.

Below is my configuration. This is what I'm using to increase the timeout: proxy_connect_timeout 3600; proxy_send_timeout 3600; proxy_read_timeout 3600; keepalive_timeout 3600; proxy_next_upstream off;

I've been trying to get this to work for over a day, so any hints are greatly appreciated. Cheers!
