nginx tomcat 访问问题

hechangsheng18 2013-12-29 11:48:58

各位大侠，小弟遇到一个问题（nginx1.5.8+tomcat6+jdk6+windows2008，服务器在美国）:
这周末前，国内（深圳）、美国等地客户客户机都能正常访问产品列表（列表数据通过ajax，调用app中的action返回）。但就在这两天深圳地区这边访问产品列表时，需要大概10分钟才能加载出来。而在福州和美国的朋友测试了下，都能正常的加载产品列表。我在深圳这边的网络环境正常，上网速度都很快，是光纤。请大侠们帮忙看看，分析下。不知是否与电信网络有关。
下面是主要配置：
nginx.conf
upstream location {
ip_hash;
server localhost:18081 weight=5;
server localhost:18082 weight=5;
}
location ~ \.(jsp|action)$ {
proxy_pass http://location;
#include proxy.conf;
}
location ~ \/(j_acegi_security_check)$ {
proxy_pass http://location;
#include proxy.conf;
}
proxy.conf
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
client_max_body_size 10m;
client_body_buffer_size 128k;
proxy_connect_timeout 300;
proxy_send_timeout 300;
proxy_read_timeout 300;
proxy_buffer_size 4k;
proxy_buffers 4 32k;
proxy_busy_buffers_size 64k;
proxy_temp_file_write_size 64k;
