i'm trying to get custom language and message for nginx error page but keep url on browser.. not success for eg: i go to url : xaluan.com/aaa/bbb.html on the time server down.. nginx will show error 502. with the same url but custom message as my language.

test 1.
I created a custom page at /usr/local/nginx/html/205.html

as following config but it show on web site when error is default nginx error at domain.com/50.html ( the content of webpage not same as i created)

error_page 502 /502.html;
location = /502.html {
root /usr/local/nginx/html;
}

test 2. Then i create same page at my www domain folder /home/xaluano/public_html/502.html but this keep redirect me to root domain.com/502.html the content now same as i created. but.. the url still not as i need

error_page 502 /502.html;
location = /502.html {
root /home/xaluano/public_html;
internal;
}

EDIT UPDATE for more detail 10/06/2012 please download my nginx config http://pastebin.com/7iLD6WQq and vhost config following: http://pastebin.com/ZZ91KiY6

== the case test..

if apache httpd service stop: #service httpd stop

then open browser go to:

xaluan.com/modules.php?name=News&file=article&sid=123456

I will see the 502 error with the same url on browser address

== Custome error page I need the config which help when apache fail .. will show the custom message tell user wail for 1 minute for service back then refress current page with same url ( refresh I can do easy by javascript ), Nginx dosent change url so java-script can work out.

any help will be great.. thank in advance
