PowerShell ISE WebRequest fails after multiple calls

Question

The following code works by itself if running from a console, but when running it using PowerShell ISE, it fails with Exception calling "GetResponse" with "0" argument(s): "The operation has timed out" after two runs. Have to restart the ISE to run it again.

$req = [System.Net.WebRequest]::CreateHttp("http://stackoverflow.com/")
$req.Timeout = 500
$req.GetResponse()

What is this limitation and is there a way to remove the limitation?

Answer 1

It seems like you have to dispose the response:

$req = [System.Net.WebRequest]::CreateHttp("http://stackoverflow.de/")
$req.Timeout = 5000
$response = $req.GetResponse()

$response.Dispose()

However, there is a built-in powershell cmdlet Invoke-WebRequest which you could also use:

Invoke-WebRequest http://stackoverflow.de/
