Hello all -

I'm attempting to do the following in nginx and having difficulty with the last step in this succession.

1) In / location, proxy_pass to Django upstream.
2) proxy_intercept_errors is on in this block and does a proxy_pass to PHP upstream if 404 is returned.
3) In PHP location block (internal), proxy_intercept_errors is on and if a 404 is returned, goes to 404 location block.
4) The 404 location block should proxy_pass to the same Django upstream, but pass /404/ to the Django app.

Everything but the final 404 proxy_pass is working fine. I can send a "bad" URL that will return a 404 from Django and PHP upstreams, but when I tail the Django app logs, the "bad" URL is what is sent to the upstream when I would like /404/ sent to the upstream. I do not need the URL to be re-written to domain.com/404/ in the client browser.

Thank you in advance for any help/recommendations.
