最近搞了個域名，想用它直接去訪問Tomcat上部署的專案，開始一直必須加上專案名稱，經過短暫配置，成功了。

訪問一次，到達登陸頁面，結果死活登入不進去，一直在登陸介面，原來是由於cookie丟失，現配置如下，完美解決問題：

server {
        listen       80;
        #listen       somename:8080;
        server_name www.XXX.cn;

        location / {
            proxy_pass http://IP:8080/projectName/;
            proxy_cookie_path /projectName/
 
 /;
           proxy_set_header   Host    $host;
           proxy_set_header   X-Real-IP   $remote_addr;
           proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
            #root   html;
            #index  index.html index.htm;
        }
        location /projectName/ {
           proxy_pass http:
 
//IP:8080/projectName/;
           proxy_cookie_path /projectName/ /;
           proxy_set_header   Host    $host;
           proxy_set_header   X-Real-IP   $remote_addr;
           proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
       }
    }
