nginx 反向代理 tomcat session cookie 不一致问题

nginx 反向代理配置文件

#PROXY-START/insect
location /insect
{
    expires 12h;
    if ($request_uri ~* "(php|jsp|cgi|asp|aspx)")
    {
         expires 0;
    }
    proxy_pass http://127.0.0.1:8080/insectCamp;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header REMOTE-HOST $remote_addr;
    
    #持久化连接相关配置
    #proxy_connect_timeout 30s;
    #proxy_read_timeout 86400s;
    #proxy_send_timeout 30s;
    #proxy_http_version 1.1;
    #proxy_set_header Upgrade $http_upgrade;
    #proxy_set_header Connection "upgrade";
    add_header X-Cache $upstream_cache_status;
    
    #Set Nginx Cache
    
    	add_header Cache-Control no-cache;
}

#PROXY-END/insect

代理可以正常运行

但是登陆的时候验证码一直提示不正确，也就是说是 Session 出了问题。

解决办法就是加上两句话

#PROXY-START/insect
location /insect
{
    expires 12h;
    if ($request_uri ~* "(php|jsp|cgi|asp|aspx)")
    {
         expires 0;
    }
    proxy_pass http://127.0.0.1:8080/insectCamp;

    # SESSION不一致问题
    proxy_cookie_path /insectCamp/ /;
    proxy_cookie_path /insectCamp /; 
 
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header REMOTE-HOST $remote_addr;
    
    #持久化连接相关配置
    #proxy_connect_timeout 30s;
    #proxy_read_timeout 86400s;
    #proxy_send_timeout 30s;
    #proxy_http_version 1.1;
    #proxy_set_header Upgrade $http_upgrade;
    #proxy_set_header Connection "upgrade";
    add_header X-Cache $upstream_cache_status;
    
    #Set Nginx Cache
    
    	add_header Cache-Control no-cache;
}

#PROXY-END/insect
