250 pts:  Persistence of cookies and authentication tickets when CHtmlView launches new IE browser windows

My clients must be authenticated with a .NET authentication ticket or cookie that persists over all browser windows.  It works correctly if I start the web application in Internet Explorer.  The authentication ticket will persist over any new window that is launched by a script on the page.

But if the user logs on from a page running in a CHtmlView, and then when the page launches a new IE browser window, the user is not authenticated in the new window and must log on in that new window.

Why is this so?  What must i do?

Hi,

  I may be way offbase here, but...

  CHtmlView is not executing an IE browser window.  It is simulating an IE browser through its MFC classes.  Therefore, the implication would be that all behavior is not the same.  

  I'm presuming the app is spawning a new window that knows nothing of cookies and whatever authentication you are requiring through the .NET.  So, while I know the MFC people told you to come here, I believe they are mistaken and you need write some code within the app to check for cookies before spawning the 'browser' window.

I will be closing this question, for I have solved the problem.

I have overrided the OnNewWindow2 event of CHtmlView.
In the event, i create a new document window, and the authentication ticket persists.

Solution:
I overrided the OnNewWindow2 event and created a new document frame having the same parent application....

void CBrowserView::OnNewWindow2(LPDISPATCH* ppDisp, BOOL* Cancel)
{
    // Get a pointer to the application object
    CWinApp* pApp = AfxGetApp();    // Get the correct document template
   
     CDocTemplate* pDocTemplate;
    POSITION pos = pApp->GetFirstDocTemplatePosition();
    pDocTemplate = pApp->GetNextDocTemplate(pos);
    ASSERT(pDocTemplate);    // Create the new frame

    CFrameWnd* pNewFrame = pDocTemplate->CreateNewFrame(GetDocument(),
                                   (CFrameWnd*)AfxGetMainWnd());
    ASSERT(pNewFrame);    // Activate the frame and set its active view
     pDocTemplate->InitialUpdateFrame(pNewFrame, NULL);

    CBrowserView* pWBVw = (CBrowserView*)pNewFrame->GetActiveView();
    ASSERT(pWBVw);
    pWBVw->SetRegisterAsBrowser(TRUE);
     *ppDisp = pWBVw->GetApplication();
}
