[ENHANCEMENTS] global 'error_page' for HTTP status codes

[rai68]

Is your feature request related to a problem? Please describe. Nope

Describe the solution you'd like Basically with NGINX or NPM I can use proxy_intercept_errors on; to use a global status page for each request where there may be an error.

error_page 404 /index_404.html;
location = /index_404.html {
  alias /data/nginx/custom/index_404.html;
  internal;
}

creates an error page here.

I feel like with Zoraxy you should be able to enable proxy intercept mode with error pages and the internal static web server.

And yea its probably not a normal thing to have global error pages since the reversed service should handle it but i like my global error pages

Describe alternatives you've considered Not really sure of an alternative perhaps use both Zoraxy and NPM behind it.
