In this article, we will explore how to use the New-AzApplicationGatewayBackendHttpSettings cmdlet in PowerShell to configure backend HTTP settings for an Azure Application Gateway. This is an essential task for any Windows engineer managing an Azure environment, as it allows for fine-tuning the behavior of the Application Gateway when forwarding HTTP requests to backend servers.

The New-AzApplicationGatewayBackendHttpSettings cmdlet is part of the Azure PowerShell module, which provides a comprehensive set of cmdlets for managing Azure resources. It allows you to create and configure backend HTTP settings for an Application Gateway, including settings such as the port number, protocol, and cookie-based affinity.

Examples:

1. Creating a new backend HTTP setting:

   $backendHttpSettings = New-AzApplicationGatewayBackendHttpSettings -Name "MyBackendHttpSettings" -Port 80 -Protocol Http -CookieBasedAffinity Enabled

   In this example, we create a new backend HTTP setting named "MyBackendHttpSettings" with port 80, HTTP protocol, and cookie-based affinity enabled.

2. Updating an existing backend HTTP setting:

   $backendHttpSettings = Get-AzApplicationGatewayBackendHttpSettings -Name "MyBackendHttpSettings" -ApplicationGateway $applicationGateway
   $backendHttpSettings.CookieBasedAffinity = Disabled
   Set-AzApplicationGatewayBackendHttpSettings -BackendHttpSettings $backendHttpSettings

   In this example, we retrieve the existing backend HTTP setting named "MyBackendHttpSettings" associated with the specified Application Gateway, disable cookie-based affinity, and update the setting.

3. Removing a backend HTTP setting:

   Remove-AzApplicationGatewayBackendHttpSettings -Name "MyBackendHttpSettings" -ApplicationGateway $applicationGateway

   In this example, we remove the backend HTTP setting named "MyBackendHttpSettings" from the specified Application Gateway.
