nginx not picking up error_page

[Guy Naor]

Hi,

I have an nginx setup to serve rails applications. But for some reason 
it's not picking up the error_page 400 404 /40x.html.

Here is part of the config file:

This is inside my location / {} config part

error_page   500 502 503 504 /50x.html;
error_page   404 400 403 /40x.html;

Here is the access log entry. Nginx is getting a 500 but just returning 
it as is (it's the exception description in rails). But I want it to go 
to the nicer 50x.html

72.211.211.12 guy.test.com - [29/Mar/2009:18:17:46 +0000] GET /testpage 
HTTP/1.1 "500" 21799 "-" "Mozilla/5.0 (X11; U; Linux x86_64; en-US; 
rv:1.9.0.7) Gecko/2009030503 Fedora/3.0.7-1.fc10 Firefox/3.0.7" "-"

The error log shown no error, btw.

Bye,

Guy.
