如何将所有请求重定向到期望一个HTML页面的另一个子域？

Question

我在一台主机中有Tomcate项目，我希望nginx重定向并传递如下请求：

ui.mysite.com                >>  www.mysite.com:2121/index_ui.html (*)
ui.mysite.com/index_ui.html  >>  www.mysite.com:2121/index_ui.html (**)
ui.mysite.com/everyThing     >>  www.mysite.com:2121/everyThing (all other)
ui.mysite.com/style.css      >>  www.mysite.com:2121/style.css
ui.mysite.com/js.js          >>  www.mysite.com:2121/js.js

我有下面的代码，但是它将所有请求重定向到www.mysite.com/everyThing

server {
    listen          80;
    server_name     you.mysite.com ; 
    rewrite ^(?!(/index_ui.html)).*$ htt://www.mysite.com/$1 temporary;
    location / {
        proxy_set_header X-Forwarded-Host $host;
        proxy_set_header X-Forwarded-Server $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass htt://www.mysite.com:2121/index_ui.html;
    }  }
