I am trying to understand how to catch 400 and 404 errors being returned  
back from my FCGI server;

How do I specify a custom error page?

I tried

error\_page 404 400 /404.html;  
location = /404.html {  
root /app/www/aderet.net/;  
}

But it still returns the FCGI Error page?

Any ideas what I may be doing wrong?

Thanks.
