nginx rewrite 添加base url

這是我目前的設(shè)置,

location /jenkins {                                                                                                                                                                                  
                # First attempt to serve request as file, then                                                                                                                                                               # as directory, then fall back to displaying a 404.                                                                                                                                          
                # try_files $uri $uri/ =404;                                                                                                                                                                 
                include             /etc/nginx/proxy_params;                                                                                                                                                 
                proxy_pass          http://localhost:8080/;                                                                                                                                                  
                proxy_read_timeout  90s;                                                                                                                                                                     
                # Fix potential "It appears that your reverse proxy set up is broken" error.                                                                                                                 
                proxy_redirect      http://localhost:8080/ http://www.example.com/jenkins;                                                                                                                
        }

這樣設(shè)置我可以訪問http://www.example.com/jenkins，但是里面所有的requests都是導(dǎo)向http://www.example.com/的，實(shí)際上應(yīng)該導(dǎo)向http://www.example.com/jenkins，所以該如何寫rewrite rule，這樣只有/jenkins不會被改變，其他的url都在前面添加/jenkins/?
