Dear Nginx Experts / Friends,

I am new to nginx. Just getting my feet wet since around 15 days.
I am sorry for this extremely long post. Just wanted to give all details
for quick understanding of the problem hence long code attachments.

I have installed CentOS 5.5 + nginx + php-fpm on linode.com VPS.
Default error_page 404 in nginx.conf for server localhost is working.

But for domain name based configuration [1] error_page is not working.
I disabled php-fpm to see if that is the problem, but still I do not see the error404.htm
page. I am also attaching my nginx.conf [2], fastcgi_params [3] & php-fpm.conf [4] for reference.
I even did a debug [5] but could not find any problem from the same.

---------------------------------------------------------------------------------------------------------------------------------

I tried all combinations of error_page in / out of the location setting before and after the
fast_cgi options etc.. Even disabling gzip and fastcgi settings but even with a plain nginx
and separate mutually4u.com server config file, i am not able to see the redirect error404.htm
page on the browser. Directly accessing the error404.htm page works fine. I am using the
server version nginx/0.8.47 as seen in the debug output along with php 5.2.14 with APC and
memcache enabled. Even after spending more than 8 hours with various options I am clueless.
I also googled a lot of code to find the cause of this problem and also searched this forum,
but could not find the cause of this simple problem.

Any help will be most appreciated. Thank you.

Regards
Ganesh
