nginx反向代理、根据浏览器分离访问

环境根据http://www.cnblogs.com/zzzhfo/p/6032095.html配置

修改LB的/usr/local/nginx/conf/nginx.conf

upstream static_pools {
     server 192.168.119.130:80;
}   
upstream dynamic_pools {
     server 192.168.119.133:80;
}

    server {
        listen       80;
        server_name  www.test.com;
        location / {
            root   html;
            index  index.html index.htm;
            proxy_set_header Host $host;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    if ($http_user_agent ~* "MSIE")      #MSIE IE浏览器
      {
        proxy_pass http://dynamic_pools;
      }
    if ($http_user_agent ~* "Firefox")    #Firefox火狐浏览器
      {
        proxy_pass http://static_pools;
      }
        }

在web01和web02上分别创建一个测试页

web01

[root@web01 www]# echo Firefox > test.html

web02

[root@web02 www]# echo "IE" > test.html 

测试、分别使用Firefox和IE浏览器访问

Firefox访问（物理机没有做hosts解析使用LB的IP访问）

查看日志

web01
