How to use pAPP to modify url in Igor's pApp.

[smooth connection]

Hi, I am playing with Igor's pAPP toolkit sample code.
My goal is intercept http request, then change it to another url.
Say from http://www.google.com to http://www.yahoo.com
I did the change in Start() method, and below is the piece of the code:

template <class StartPolicy, class ThreadModel>
inline STDMETHODIMP CInternetProtocol<StartPolicy, ThreadModel>::Start(
LPCWSTR szUrl, IInternetProtocolSink *pOIProtSink,
IInternetBindInfo *pOIBindInfo, DWORD grfPI, HANDLE_PTR dwReserved)
{

ATLASSERT(m_spInternetProtocol != 0);
if (!m_spInternetProtocol)
{
return E_UNEXPECTED;
}

//Here is my addition
static bool b = false;
if (!b)
{
b = true;
szUrl = L"http://www.google.com";
}
//end of addition
return StartPolicy::OnStart(szUrl, pOIProtSink, pOIBindInfo, grfPI, dwReserved, m_spInternetProtocol);
}

But it never works. Only first request is send as google, and all the sub request is still from yahoo.com. and the browser control cannot show the right page.

Did I miss something?

Another related question: if i also want to modify the cookie with my own one and send along with modified url, where is the right place to add the cookie?

Thanks,
