Phil's questions

I have two use cases:

1. HTTPD is a proxy for a Tomcat application

2. HTTPD is a proxy for a PHP application

For compliance and security needs all 50x errors must be rewritten to 503 prior to sending back to a client. Exposing 50x errors leaks information about your application, so is bad practice.

I still wish to see 500s in the HTTPD log files, but must rewrite the HTTP error sent back to clients.

Constraints:

1. Using an external program or other application is out of the question, i.e. varnish, pound, nginx et al.

2. I do not wish to send back an error page, I only need to rewrite the HTTP status. i.e. change the HTTP/1.1 500 to a 503 in the following:

   [user@host]$ curl -I http://localhost:8080/500.php
   HTTP/1.1 500 Internal Server Error
   <OUTPUT OMITTED>
   

Is this possible?

Note: I created error pages with:

for http_status in 401 403 500 501 503; do
    echo -e "<?php\nhttp_response_code(${http_status});" > ${http_status}.php
done
