Nginx错误

首先我们来解决last和break的区别：

root    html;
index    index.html;
location /c/ {
	rewrite .* /;
}

location /a/ {
	rewrite .* /c/ last;
}

location /b/ {
	rewrite .* /c/ break;
}

访问localhost/a/时访问的是html/index.html
访问localhost/b/时访问的是html/c/index.html

好了，然后我们修改配置：

location /a/ {
	rewrite .* /a/ last;
}

这种情况访问时，系统提示500错误，错误日志：

rewrite or internal redirection cycle while processing "/a/", client: 127.0.0.1, server: localhost, request: "GET /a/ HTTP/1.1", host: "localhost"

那么下面这个情况呢：

location /b/ {
	rewrite .* /b/ break;
}

这个情况就比较复杂了

第一种情况：路径html/b/不存在时，提示404

"D:\Program Files (x86)\nginx-1.4.7/html/b/index.html" is not found (3: The system cannot find the path specified), client: 127.0.0.1, server: localhost, request: "GET /b/ HTTP/1.1", host: "localhost"

第二种情况：路径html/b/存在，但是没有index.html时，提示403

directory index of "D:\Program Files (x86)\nginx-1.4.7/html/b/" is forbidden, client: 127.0.0.1, server: localhost, request: "GET /b/ HTTP/1.1", host: "localhost"

第三种情况：路径和文件都存在时，能不能访问呢？答案是不能，提示500

rewrite or internal redirection cycle while internally redirecting to "/b/index.html", client: 127.0.0.1, server: localhost, request: "GET /b/ HTTP/1.1", host: "localhost"

搞的我也有点懵了。而且使用了break也会匹配到其他location，难道是Windows的问题。
