Difference between WebCommitDelay and IISCommitDelay

Question

What is the difference between WebCommitDelay and IISCommitDelay?

MS docs says the same for both: Instructs the IIS configuration system to delay the commitment of changes.

So what should I prefer and why? It looks like they have some differences indeed, because if I use WebCommitDelay, I can't use New-WebApplication ... -Force if the same application is exists, but I can do this if I use IISCommitDelay.

Answer 1

As far as I know, the IISAdministration PowerShell module which was a new way to manage IIS.

This module included numerous improvements over the existing WebAdministration cmdlets.

So the IISCommitDelay is the new method which is used to management the IIS.
