# Application Rule Details

Here are some custom rules, let's have a look at the details. Rule 11 is an interesting example.

This rule makes a conditional redirection based on the Accept-Language (request) header.

So when the Accept-Language header contains the word zh, the Chinese language, no matter simplified or traditional,

and the URI equals to /,

and the host name equals to,

then we do a redirection to /cn/ with the status code 302 and also the current scheme and host name. So this is an example of doing internationalization or localization. And we also have a similar rule for (the case) Accept-Language contains the word "en" (for English).
