Rewriting

[Bozhidara Marinchovska]

Hello,

Because you placed root inside the location /.
As http://wiki.nginx.org/Pitfalls your root should also be placed in the 
server block.

Example:

   server {
                 listen          80;

                 root            /usr/local/www/test;

                 if ($remote_addr ~ '192.168.1.25')
                 {
                     rewrite ^/(.*)$ /unav/index.html break;
                 }

                 location / {
                 index index.html;
                 }

                 location /index.php {
                         ...
                 }

         }
}

Example content of index.html in /usr/local/www/test is "test"
Example content of index.html in /usr/local/www/test/unav is "unav dir"

Let we say your server is on 192.168.1.24:
- when you access http://192.168.1.24/index.html from host 192.168.1.25 
you will see in the browser index with content "unav dir".
- when you access http://192.168.1.24/index.php from host 192.168.1.25 
you will see in the browser index with content "unav dir".
- when you access http://192.168.1.24/index.html (or index.php) from 
another host for example 192.168.1.24 or 192.168.1.23 you will see the 
content of index.html (index.php) from your config. In the example is 
content "test" of index.html and phpinfo() in the index.php.
