Your approach worked fine for me! Thanks for the help.

Horever, without this "add_header" modification and with
"proxy_intercept_errors on;", I've two situations:
* without "error_page 301 302 /30x.html;" directive configured: I
receive the HTTP "location" header from my NGINX;
* with "error_page 301 302 /30x.html;" directive configured: I don't
receive the HTTP "location" header from my NGINX;

If "proxy_intercept_errors" handling does not copy any response
headers from the original response, why is this HTTP "location" header
present with "error_page 301 302 /30x.html;" directive configured in
my system?

I really don't understand why it happens.

Well, thanks again.
Fabiano
