Apache 反向代理及负载均衡配置+正则分组匹配业务需求：
国外网站接口无法访问国内的服务器，通过香港服务器配置反向代理服务器解决国内国外互通访问问题
配置原理图：
apache主配置文件：
#Url Proxy
Include conf/extra/proxy-url.conf
extra目录下配置文件：
proxy-url.confproxy-url.conf
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_connect_module modules/mod_proxy_connect.so
LoadModule proxy_http_module modules/mod_proxy_http.so
LoadModule proxy_balancer_module modules/mod_proxy_balancer.so
LoadModule lbmethod_byrequests_module modules/mod_lbmethod_byrequests.so
LoadModule lbmethod_bytraffic_module modules/mod_lbmethod_bytraffic.so
LoadModule lbmethod_bybusyness_module modules/mod_lbmethod_bybusyness.so
LoadModule slotmem_shm_module modules/mod_slotmem_shm.so
LoadModule rewrite_module modules/mod_rewrite.so
ProxyRequests Off
