Discussion: Autodetect Proxy Server and set in Invoke-TlsWebRequest?

[potatoqualitee]

This is what I'm doing in another module

$proxy = (Get-ItemProperty -Path "Registry::HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings").ProxyServer

    if ($proxy -and -not ([System.Net.Webrequest]::DefaultWebProxy).Address) {
        [System.Net.Webrequest]::DefaultWebProxy = New-object System.Net.WebProxy $proxy
        [System.Net.Webrequest]::DefaultWebProxy.Credentials = [System.Net.CredentialCache]::DefaultNetworkCredentials
    }

Could you just use [System.Net.WebRequest]::GetSystemWebproxy() to get it instead of looking at the regkey?

this would probably work just for "fixed" proxies. Evaluating, e.g., a PAC file would be .... a better fix, if .net has already a method for it ?

[potatoqualitee]

thx wassa pac and would this negatively impact users or just not cover enough of them?

Should we do [System.Net.WebRequest]::GetSystemWebproxy() with a config option to disable?
