    @Shiva Kakileti , The Keep-Alive timeout in the Application Gateway v1 SKU is 120 seconds and in the v2 SKU it's 75 seconds. The TCP idle timeout is a 4-minute default on the frontend virtual IP (VIP) of both v1 and v2 SKU of Application Gateway.
    You can configure the TCP idle timeout value on v1 and v2 Application Gateways to be anywhere between 4 minutes and 30 minutes. You can set the TCP idle timeout value of the public IP through PowerShell by running the following commands: 

        $publicIP = Get-AzPublicIpAddress -Name MyPublicIP -ResourceGroupName MyResourceGroup  
    $publicIP.IdleTimeoutInMinutes = "15"  
    Set-AzPublicIpAddress -PublicIpAddress $publicIP
