nginx rewrite flag参数详解

[billfeller]

last stops processing the current set of ngx_http_rewrite_module directives and starts a search for a new location matching the changed URI; break stops processing the current set of ngx_http_rewrite_module directives as with the break directive; redirect returns a temporary redirect with the 302 code; used if a replacement string does not start with “http://” or “https://”; permanent returns a permanent redirect with the 301 code.

last： 使用了last 指令，rewrite 后会跳出 location 作用域，重新开始再走一次刚刚的行为。 break：使用了break 指令，rewrite 后不会跳出 location 作用域，它的生命也在这个location中终结。

permanent：301 Moved Permanently redirect：302 Moved Temporarily

总结 last与break对前端是透时的，主要体现在服务器端的处理流程的区别； permanent与redirect则是通过返回3xx给前端从而进行重定向；

如下图显示permanent与redirect在浏览器端的区别：
