    .SYNOPSIS
    Gets the HTTP redirect settings for a website or virtual directory/application under a website.
    
    .DESCRIPTION
    Returns a `Carbon.Iis.HttpRedirectConfigurationSection` object for the given HTTP redirect settings.  The object contains the following properties:
    
     * Enabled - `True` if the redirect is enabled, `False` otherwise.
     * Destination - The URL where requests are directed to.
     * HttpResponseCode - The HTTP status code sent to the browser for the redirect.
     * ExactDestination - `True` if redirects are to destination, regardless of the request path.  This will send all requests to `Destination`.
     * ChildOnly - `True` if redirects are only to content in the destination directory (not subdirectories).
