nginx 重写Response Header Content-Language

最近做SEO优化,要求返回正确的Content-Language;

response.setHeader("Content-Language", "ja");//这个设置没用,这个值跟操作系统有关

 于是在nginx重写这个值,简略配置如下;

环境 :http://localhost/french;http://localhost/japanese........等;

        
location /{
	proxy_hide_header 'Content-Language'; #隐藏掉之前的值
	if ($request_uri ~* "/china"){ #根据不同的国家添加不同的值
		add_header Content-Language cn;
	}
	if ($request_uri ~* "/japanese"){
		add_header Content-Language ja;
	}
	if ($request_uri ~* "/french"){
	        add_header Content-Language fr;
	}
	proxy_pass http://home_server;
			
}
		
rewrite /china /test/index.do?locale=cn&custom=1 last;
rewrite /french /test/index.do?locale=fr&custom=2 last;
rewrite /japanese /test/index.do?locale=ja&custom=3 last;
rewrite ^/(.*) /test/index.do?locale=$1&custom=4 last;

以上代码在nginx-1.5.3 windows平台上测试通过.

 请看官方文档:

Note that for headers other than Last-Modified, it just appends a new header entry to the output header list. So you can't use this directive to rewrite existing headers likeServer. Use the headers_more module for it.

大概意思是说add_header这个参数不能修改 Last-Modified 除这个之外的值,如果你要修改,使用headers_more 这个扩展.由于我在windows上测试的,没法编译扩展到nginx,so用上面的办法!(╰_╯)#..
