Replace string in content

Server NGINX
1

Hello,

I just add these rows to the default config
(/usr/local/nginx/conf/nginx.conf) at the end of the location section:

    location / {
        root   html;
        index  index.html index.htm;
    sub_filter      nginx 'newstring';
    sub_filter_once off;
    subs_filter_types text/html text/css text/xml;
    subs_filter nginx 'newstring' i;
    }

But if I see the http://localhost in firefox there is no “newstring”
instead of “nginx”.
Why? I expected to replace the nginx string…

/usr/src/nginx/nginx-1.2.4# /usr/local/nginx/sbin/nginx -V

Why I can not replace string in pages? Can I debug what happening? Help
me,
please.

I will check it with the debug mode when I get home, thanks.
I use the default config. I just add the filter rows all other lines are
default. That’s why I don’t understand what can be wrong.

Probably you have a problem in your config, but since you have provided
only
small part of it, then it’s impossible to determine.

Can I debug what happening? Help me, please.

Yes, you can: A debugging log

I just change the default port 80 to 8869 and the reprace content
started
to work!
Then I wrote the port to 80 again and the filter is still working.
Incredible…
