MSXML2.XMLHTTP is preferred over MSXML2.ServerXMLHTTP and WinHttp.WinHttpRequest.5.1 in simple client to server situations

MSXML2.XMLHTTP respects system proxy settings. It opens URL the same way your browser opens.
MSXML2.ServerXMLHTTP WON’T work if your browser has proxy settings. It provides options to set up proxies grammatically.
WinHttp.WinHttpRequest.5.1 will disregard system proxy settings and connect directly.
