Really, truly controlling Nginx error pages

[pk899]

I have googled and searched through this forum. 

But this syntax in the config file does NOT help: 


    # recursive_error_pages on;
    error_page 403 404 500 502 503 504  /error.htm;


It works sometimes, but often it just shows me the stock Nginx page. 

How do I avoid this once and for all, or is this impossible?
