解析

• 根据上述示例，解析如下

路径	类型	重写	描述	备注
/exact	exact		location ~* "^/exact"	Rules中存在一个Rewrite，所有匹配类型变成正则匹配
/user	exact	/something	location ~* "^/user" rewrite "(?i)/user" /something break;	变成正则匹配，重写代理路径
/app	prefix		location ~* "^/app/" rewrite "(?i)/app/" /app break; location ~* "^/app"	前缀匹配
/something(/|$)(.*)	regex	/$2	location ~* /something(/$)(.*) rewrite "(?i)/something(/$)(.*)" /$2 break;	正则匹配，按照()分组，$2代表(.*)部分
/exact	exact		location = /exact	Rules没有Rewrite，生成的绝对匹配
