in C#/Powershell - Is it possible to change the Idle TimeOut for an IIS Application Pool?

Question

I want to disable the idle timeout (Set it to Zero) of an application pool and I want to perform this at setup time, is it possible to perform this action from C# or PowerShell?

Answer 1

If you are using PowerShell 2 or later, you should have access to Set-ItemProperty. You'll also want to load the WebAdministration module.

You can then do (example taken from here)

Set-ItemProperty ("IIS:\AppPools\$name") -Name processModel.idleTimeout -value ( [TimeSpan]::FromMinutes(0))

and verify that the value was changed with

Get-ItemProperty ("IIS:\AppPools\$name") -Name processModel.idleTimeout.value

Answer 2

@R0MANARMY's answer (currently the most popular) didn't work for me. It runs fine, but the subsequent check shows that the idle timeout is unchanged.

Based on this blog post, that answer modifies an in-memory copy of the object. I modified the sample code in R0MANARMY's answer as:

Get-ChildItem IIS:\AppPools\$name | ForEach { $_.processModel.IdleTimeout = [TimeSpan]::FromMinutes(0); $_ | Set-Item; }
