rewrite 优先级较高，导致路径已经先被重写了。可以都改用location去匹配。

    location ~ /(test1|test2|test3|test4) {
            proxy_set_header Host "test.com";
            proxy_set_header X-Forwarded-For $remote_addr;
            proxy_pass http://127.0.0.1:8080;
    }

    location ~* ^/(.*)\.(zip|js|ico|css|xml|txt|html|swf|apk|ipa|plist)$ {
        rewrite ^/(.*)$ /index.php last;
    }

    location ~ \index.php$ {
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include fastcgi_params;
        fastcgi_hide_header X-Powered-By;
    }  

不过确定 静态文件也要重写到 index.php吗？
