I need to honor the web browser's list of language preferences. Supported languages are English and French. For example: http_accept_language="jp-JP;fr;en-US;en" redirects to a directory called /French/. How can I do this with rewrite rules in my .htaccess file?

推荐答案

我不会使用mod_rewrite可以实现，但更强大的语言。因为接受语言的是加权值的列表（见质量值）和标识符之一的发生并不意味着它是pferred在另一个价值$ P $（尤其是 Q = 0 表示不接受的话）。

I wouldn’t use mod_rewrite for this but a more powerful language. Because Accept-Language is a list of weighted values (see quality value) and the occurrence of one of the identifiers does not mean that it’s preferred over another value (especially q=0 means not acceptable at all).

前面已经说了，使用更强大的语言比mod_rewrite的，分析的价值列表，找到了preferred选项和可选项的最佳匹配。

As already said, use a more powerful language than mod_rewrite, parse the list of value and find the best match of preferred options and available options.
