How do I prevent a Gateway Timeout with FastCGI on Nginx

Question

I am running Django, FastCGI, and Nginx. I am creating an api of sorts that where someone can send some data via XML which I will process and then return some status codes for each node that was sent over.

The problem is that Nginx will throw a 504 Gateway Time-out if I take too long to process the XML -- I think longer than 60 seconds.

So I would like to set up Nginx so that if any requests matching the location /api will not time out for 120 seconds. What setting will accomplish that.

What I have so far is:

    # Handles all api calls
    location ^~ /api/ {
        proxy_read_timeout 120;
        proxy_connect_timeout 120;
        fastcgi_pass 127.0.0.1:8080;
    }

Edit: What I have is not working :)

Answer 1

Proxy timeouts are well, for proxies, not for FastCGI...

The directives that affect FastCGI timeouts are client_header_timeout, client_body_timeout and send_timeout.

Edit: Considering what's found on nginx wiki, the send_timeout directive is responsible for setting general timeout of response (which was bit misleading). For FastCGI there's fastcgi_read_timeout which is affecting the fastcgi process response timeout.

HTH.
