SPE remoting proxy uses HTTP instead of HTTPS

[sitecorepm]

Expected Behavior

When calling "New-ScriptSession" with a URL using HTTPS, the resulting $session.Connection.Proxy.Url should also use HTTPS.

Actual Behavior

When calling "New-ScriptSession" with a URL using HTTPS, the resulting $session.Connection.Proxy.Url is returning HTTP.

Steps to Reproduce the Problem

This is a problem specific to our networking setup.

Client ----(HTTPS)----> LB ----(HTTP)----> Server

Our load balancer (LB) hosts our SSL cert and does NOT re-encrypt traffic to the server, therefore the WSDL file response uses HTTP instead of HTTPS as the service URL.

To work around this issue, I added the following code to the New-ScriptSession.ps1 (at line 119)

$proxy = New-WebServiceProxy @proxyProps
if($Credential) {
    $proxy.Credentials = $Credential
} elseif ($UseDefaultCredential.IsPresent) {
    $proxy.UseDefaultCredentials = $true
}

# -------------- WORKAROUND----------------------------------------
# If the returned proxy URL doesn't match schemes, force it
# This can happen due to load balancers hosting SSL certs instead of the server 
if (!$proxy.Url.StartsWith($uri.Scheme + "://")){
    Write-Verbose "Changing proxy URL scheme to: $($uri.Scheme)"
    $proxy.Url = $proxy.Url -replace "^https?", $uri.Scheme
}
# -------------- END WORKAROUND----------------------------------------

if($Timeout -gt 0) {
    $proxy.Timeout = $Timeout * 1000
}
