nginx proxy_pass末尾神奇的/

http://otherserver;和http://otherserver/;有什么区别呢？

location /service/ {
proxy_pass http://otherserver;
proxy_next_upstream error timeout invalid_header http_500 http_503 http_404;
}

location /service/ {
proxy_pass http://otherserver/;
proxy_next_upstream error timeout invalid_header http_500 http_503 http_404;
}
同样访问：http://neverstay.com/service/add.php
前者配置，在后端的机器，收到的是http://neverstay.com/service/add.php
后者配置，在后端的机器，收到的是http://neverstay.com/add.php

如果换成下面这样，会报错：
location ~ ^/(service)/ {
proxy_pass http://otherserver/;
proxy_next_upstream error timeout invalid_header http_500 http_503 http_404;
}
"proxy_pass" may not have URI part in location given by regular expression, or inside named location, or inside the "if" statement, or inside the "limit_except" block in nginx.conf:

但是，这样就没问题了：
location ~ ^/(service)/ {
proxy_pass http://otherserver;
proxy_next_upstream error timeout invalid_header http_500 http_503 http_404;
}
