When I try to use the HtmlToPdf.ConvertUrl function for a 'view' of my SPA I get a pdf of the login page.

I tried using the HtmlToPdfSession approach (Loading and submitting the login page) and I also tried adding authentication and session cookies to HtmlToPdf.Options.Cookies, and then using the HtmlToPdf.ConvertUrl.
In both cases I get a pdf of the login page (most likely because of a redirect, because the call is not authenticated)

The app uses angular routing, and web-api for the server calls, and needs authentication and session to get the data.

code for first approach:
using (HtmlToPdfSession session = HtmlToPdfSession.Create())
{
session.LoadUrl("login.html");
session.Fill("username", Email);
session.Fill("password", Password);
session.Submit("btnLogin");
session.LoadUrl("http://localhost:34537/reportParticipant/23/122"); // the secure page
session.RenderAsPDF(stream); //StreamContent
}

code second approach:
foreach (string CookieName in HttpContext.Current.Request.Cookies.Keys)
{
System.Net.Cookie Cookie = new System.Net.Cookie(CookieName, HttpContext.Current.Request.Cookies[CookieName].Value);
HtmlToPdf.Options.Cookies.Add(Cookie);
} //the Request.Cookies are HttpCookies
HtmlToPdf.ConvertUrl("http://localhost:34537/reportParticipant/23/122", stream); //StreamContent

So both methods redirect me to the login page. I also have no idea if I can debug the calls done by your dll.

Anybody any thoughts on this?
