用户要求将原来的多个文件合并成一个ps1文件实现web站点的自动部署，在合并过程中遇到两个问题：
1. powershell 不区分大小写，所以在变量命名时一定要注意；
2. 在合并中遇到这个异常：
Exception setting "Protocol": "The configuration object is read only, because it has been committed by a call to ServerManager.CommitChanges(). If write access is required, use ServerManager to get a new reference."
At C:\v-zhdu\code\WebsiteDeployment\Website_Deployment.ps1:76 char:11
+ $bind. <<<< Protocol = $Binding.Protocol
+ CategoryInfo : InvalidOperation: (:) [], RuntimeException
+ FullyQualifiedErrorId : PropertyAssignmentException
根据提示，查看脚本，发现对站点的设置提交变化后，需要重新获取新的引用才可以获得写的权限，具体参见下面的script。
Website_Deployment.ps1:
