FIX: POST Data Is Truncated When You Call IWebBrowser2::Navigate

	VARIANT vFlags = {0};
	VARIANT vPostData = {0};

	// Test data length.
	int len = 6;

	// Create test data.
	char* data = new char[len];

	// Copy a string, including its NULL character.
	memcpy(data, "hello", len);
	data[2] = '\0';
	// The data now contains {he\0lo\0}. There is an embedded NULL character. 

	// Put data into safe array.
	LPSAFEARRAY psa = SafeArrayCreateVector(VT_UI1, 0, len);
	if (!psa)
		return;
	LPSTR pPostData;
	HRESULT hr=SafeArrayAccessData(psa, (LPVOID*)&pPostData);
	memcpy(pPostData,data,len);
	hr = SafeArrayUnaccessData(psa);

	// Package the SafeArray into a VARIANT.
	V_VT(&vPostData) = VT_ARRAY | VT_UI1;
	V_ARRAY(&vPostData) = psa;         
	
	// Get Headers.
	VARIANT vHeaders = {0};
	V_VT(&vHeaders) = VT_BSTR;         

	// Specify a binary Content-Type.
	V_BSTR(&vHeaders) = SysAllocString(

		L"Content-Encoding: gzip\r\n");

	// Navigate, and POST the data. http://myserver/myasp.asp 
	// is an Active Server Pages page that expects POST data.
	// m_pBrowserApp is declared as IWebBrowser2*
	hr = m_pBrowserApp->Navigate(L"http://myserver/myasp.asp", &vFlags,
