Answer 1

In my case, I had to do few more tweaks along with using UrlAsPdf(). I have narrowed down the issue to the cookie collection that I was adding. So I tried just adding the cookie that I needed, and the issue was resolved. Following is the sample code that I have used.

        var report = new UrlAsPdf(url);

        Dictionary<string, string> cookieCollection = new Dictionary<string, string>();
        foreach (var key in Request.Cookies.AllKeys)
        {
           if (Crypto.Hash("_user").Equals(key))
           {
              cookieCollection.Add(key, Request.Cookies.Get(key).Value);
              break;
           }
        }
        report.Cookies = cookieCollection;
        report.FormsAuthenticationCookieName = FormsAuthentication.FormsCookieName;

Answer 2

I ended up using UrlAsPdf() instead of ActionAsPdf() and it works. Seems there may be some issues with the ActionAsPdf() and I have filed a bug with Rotative project on GitHub. The ActionAsPdf() is still marked as beta, so hopefully it get's fixed in future versions or by the community.
