intercepting upstream error with nginx

Question

My app runs with nginx and uwsgi (python). My aim is to drop a connection (as explained here) e.g. when the python app decides to do so.

Is there a nginx parameter to \"

Answer 1

It turns out the answer is simpler than I thought - use the uwsgi_intercept_errors directive.

Firstly, from the upstream app (in my case python) return 444.

Secondly, configure nginx as follows:

location / {
    uwsgi_pass                myapp;
    include                   uwsgi_params;
    [...]

    uwsgi_intercept_errors  on;
    error_page 444 @drop;
}

location @drop {
    return 444;
}
