Azure Application Gateway (4) 设置URL路由

赵小黑

　　《Windows Azure Platform 系列文章目录》
　　本文将介绍如果使用Azure PowerShell，创建Azure Application Gateway URL Routing
　　请读者在使用之前，请先查看笔者之前的文章：Azure Application Gateway (3) 设置URL路由，熟悉相关的内容
　　注意：Azure Application Gateway必须在ARM模式下才可以创建。
　　另外PowerShell模式下，和Portal创建的不一样。
　　PowerShell模式，并不需要先创建81端口，再创建80端口。PowerShell直接可以使用80端口设置URL Routing

#手动创建Virtual Network
