Hi all!
I does some rules for various web errors, that rules shows a custom error page:

error_page 500 502 503 504 /50x.html;
location = /50x.html
{
root /etc/nginx/_conf/error-page;
}

error_page 404 /404.html;
location = /404.html
{
root /etc/nginx/_conf/error-page;
}

That's ok but there is a way to add some informations about the error in the pages? In apache there was some "apache-code" to include in the HTML page to add the web server output error in the html page, there is something like it in nginx?

thank's
