Catchall redirect to error page

Question

This is a continuation of my other post: Catch all VirtualHost not working.

I have got the catchall VirtualHost working. But know how do I get it to redirect a custom error page such as 404.

In my VirtualHost I add Redirect 404 /, it takes me to the default 404 page. But when I enable ErrorDocument 404 /errors/index.php I get the following error

Not Found The requested URL / was not found on this server. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request. 

Below is my catchall config

<VirtualHost *:80> DocumentRoot /var/www/main ServerName null Redirect 404 / ErrorDocument 404 /errors/index.php ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined </VirtualHost> 

Answer 1

That's because your Redirect 404 / affects even when trying to access /errors/index.php.

When giving 404 Not Found, you don't need to redirect everything to the root. I would suggest giving the human readable error message for non-existing virtual host at / i.e. /index.html as a normal 200 OK and use ErrorDocument 404 / to give the same content as 404 for all other URLs. The location doesn't need to change when you have already given 404 Not Found.

<VirtualHost *:80> ServerName null DocumentRoot /var/www/main ErrorDocument 404 / ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined </VirtualHost>
