Redirect 403 HTTP status return code to 404


403 (forbidden) HTTP status code gives a clue about a correct path, and you don’t have permission to access it. This confirms file/folder exists and it’s restricted.

Thus, 403 allows the hacker to know more about your file system structure and room for security vulnerabilities.

It’s a good idea to redirect 403 return code to 404 (not found), so there is no room for a guess. This is often asked to implement in the payment industry or transactional application production system.

There are multiple ways to get this done and following I’ve explained doing in Apache HTTP, Nginx.

Note: take a backup of the necessary configuration file before modifying. And if possible, test in non-production first.

Apache HTTP

We will use ErrorDocument directive to achieve this

  • Create a file at DocumentRoot level which will be served at 404
  • Let’s name the file 404
  • Add the following in httpd.conf file
ErrorDocument 403 /404

Above, I am instructing Apache to serve /404 file whenever 403 occurred

  • Save the configuration file and restart Apache to test it


Let’s use error_page directive to get this done

  • Create a file name called 404.html
  • Add the following in server section under Nginx configuration file
error_page 404 /404.html;
error_page 403 =404 /404.html;

Above, in the first line, Nginx will serve /404.html whenever file not found and the second line, /404.html will be served whenever requested resources return 403.


You can use the Custom Error Pages plugin which allows you to setup a custom page for 401 and 403 status code.
