You can get the cookies using the ServerXMLHTTP object to create an XHR, e.g.:
function getCookie(URL) {
var response;
var XmlHttpRequest = Sys["OleObject"]("MSXML2.ServerXMLHTTP.3.0");
XmlHttpRequest.open("GET", URL, false);
XmlHttpRequest.send();
try {
response = XmlHttpRequest.getAllResponseHeaders();
} catch (e) {
response = "Error";
}
XmlHttpRequest = null;
return response;
}
function TESTCookie() {
}
This actually shows you all the headers, I'll leave it to you to parse the cookies from the response:
