Hey all,

I’m currently using Nginx & HAProxy with a Rails Application on the  
backend (using mongrels).

I’ve configured my Nginx config file with a custom 50x error page:

error\_page 500 502 503 /500.html;  
location = /500.html {  
internal;  
}

If I shut my mongrels off and try to access the page, I get the default  
503 error page that comes with Nginx, not my custom 500.html page.  
Turning on my mongrels and turning off the database generates a 500  
error and I get the default 500 error page as well.

However, I also have a similar declaration for a 504 timeout or a 404  
page not found error and they work just fine.

error\_page 504 /504.html;  
location = /504.html {  
internal;  
}

error\_page 404 /404.html;  
location = /404.html {  
internal;  
}

I verified that the 500.html file exists and has the proper permissions.  
Am I missing something?

Thanks in advance
