Application Gateway: To remove (.cer) files via Azure Portal
When we want to remove an unused expired certificate (.cer) file from Application Gateway, we will have to use the cmdlet to remove them. It seems only to support the cmdlet to remove them using PowerShell or Azure CLI.
I know we can remove the certificate from HTTP settings using Portal, but it remains at Application Gateway. (It means we have to see a lot of unused certificate on the list in a HTTP setting.)
This is a simple request, that we want to remove their certificate (.cer) files not only just using the cmdlet but also via Azure Portal as well.
