Forum: NGINX replace string in content

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
nginx version: nginx/1.2.4
built by gcc 4.4.3 (Ubuntu 4.4.3-4ubuntu5.1)
TLS SNI support enabled
configure arguments: --with-pcre-jit --with-debug --with-file-aio
--with-http_addition_module --with-http_dav_module 
--with-http_flv_module

--with-http_secure_link_module --with-http_stub_status_module
--with-http_ssl_module --with-http_sub_module
--add-module=/usr/src/nginx/ngx_http_substitutions_filter_module/

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

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

Yes, you can: http://nginx.org/en/docs/debugging_log.html

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.

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...
