Custom 500 error page while using nginx proxying
By Richard Templet

I was working with our customer Paper Source to setup a 500 error page that looked like the rest of the site when I ran into something interesting. I went through the nginx configuration and added this line to allow for a custom 500 error page just like I had done for the custom 404 error page.
error_page 500 = /cgi-bin/paper/500.html;
What I noticed when I forced the site to create an Internal Server Error was that I was still getting the ugly normal Apache version of the 500 error page. It seemed like nginx was ignoring the error_page directive. I did some searching and found out that you have to use the proxy_intercept_errors directive.
proxy_intercept_errors on;
This directive allows nginx to recognize the 500 error code being returned from Apache and run its own directives to display the right page.
