Apache根据URL路径进行转发

根据URL的PATH进行转发，适合没有域名的状况下，例如：
     http://127.0.0.1/support       转到 http://192.168.1.251:8008/support 
     http://127.0.0.1/gdForestry  转到 http://192.168.1.251:9007/gdForestry 

首先启用代理模块，去掉httpd.conf中的注释：

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so

而后配置虚拟主机，重启完成（这里用的Apache2.4，语法稍有不一样）：

<VirtualHost 127.0.0.1:80>
    ServerAdmin webmaster@dummy-host.example.com
    ServerName 127.0.0.1
    ProxyRequests Off
    ProxyPreserveHost On
    <Proxy *>
        Require all granted
    </Proxy>
    ProxyPass /support http://192.168.1.251:8008/support
    ProxyPass /gdForestry http://192.168.1.251:9007/gdForestry
    ProxyPassReverse /support http://192.168.1.251:8008/support
    ProxyPassReverse /gdForestry http://192.168.1.251:9007/gdForestry
    ErrorLog "logs/test.localhost-error_log"
    CustomLog "logs/test.localhost-access_log" common
</VirtualHost>

若是不须要配置在虚拟主机，要对全局进行转发，则直接配置在httpd.conf最后添加：

ProxyPass /cas http://192.168.0.206:9090/cas
ProxyPassReverse /cas  http://192.168.0.206:9090/cas
