How do I decode data returned in the Remote Resources URL (webfeed.aspx) of an RDP server?

Question

How do I decode the rdweb/feed/webfeed.aspx content from a Microsoft remote desktop(RDP) server?

I am having difficulty locating the encoding of the webfeed.aspx or more specifically https:// RDP url /rdweb/feed/webfeed.aspx url of the RDP client. In Microsoft's RDP client, the data resolves to references to directories and applications that can be used as shortcuts for the RDP connection.

The file that I get appears to be a base64 encoded file. From what I have read, this should be an XML file that describes the resources, but it seems to be compressed or encoded somehow. I am having no issue getting the data. I can read it via a browser (though not understand it) and Microsoft's RDP client is pulling the data appropriately, so the data is good. I need to decode/process the data because I am extending an open source RDP tool to do the same as Microsoft's RDP client.

Here is an example,from the text file from a test server's rdweb/feed/webfeed.aspx

Have you tried something like this?

HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create("https://RDPurl/rdweb/feed/webfeed.aspx");

HttpWebResponse httpWebResponse = (HttpWebResponse)httpWebRequest.GetResponse();

string connectionXml;

using (StreamReader streamReader = new StreamReader(httpWebResponse.GetResponseStream()))
{
    connectionXml = streamReader.ReadToEnd();
}

More detailed code is here.

The resulting connectionXml string should be Resource List Syntax.
