IInternetSecurityManager::MapUrlToZone method

Gets the zone index for the specified URL.

Syntax


HRESULT MapUrlToZone(
  [in]   LPCWSTR pwszUrl,
  [out]  DWORD *pdwZone,
  [in]   DWORD dwFlags
);

Parameters

pwszUrl [in]

A string value that contains the URL. Compare to MapUrlToZoneEx2.

pdwZone [out]

An unsigned long integer variable that receives the zone index.

dwFlags [in]

An unsigned long integer value that specifies MapUrlToZone Flags to control the mapping.

Return value

Returns E_INVALIDARG if pdwZone is set to NULL or when the value specified in the pwszUrl parameter refers to a local file. Otherwise, S_OK is returned.

Remarks

Security Warning:  Incorrect implementation of this method can compromise the security of your application. A custom implementation of IInternetSecurityManager::MapUrlToZone should return only zones for URLs that the default application cannot or should not handle. For all other URLs, this method should return INET_E_DEFAULT_ACTION. Attempting to duplicate the default implementation can result in the incorrect mapping of zones and might leave users susceptible to spoofing or elevation of privilege attacks. Review Security Considerations: URL Security Zones API before you contine.

Examples

The following example instantiates the default security manager to determine the correct zone for the input URL, szUrl.


const char *rgZoneNames[] = { "Local", "Intranet", "Trusted", "Internet", "Restricted" };

IInternetSecurityManager* pInetSecMgr;
HRESULT hr = CoCreateInstance(CLSID_InternetSecurityManager, NULL, CLSCTX_ALL,
                        IID_IInternetSecurityManager, (void **)&pInetSecMgr);   
if (SUCCEEDED(hr))
{
    DWORD dwZone;
    hr = spInetSecMgr->MapUrlToZone(szUrl, &dwZone, 0);
    if (hr == S_OK)
    {
        if (dwZone < 5)
            printf("ZONE: %s (%d)\n", rgZoneNames[dwZone], dwZone);
        else
            printf("ZONE: Unknown (%d)\n", dwZone);
    }
    else
        printf("ZONE: Error %08x\n", hr);
        
    pInetSecMgr->Release();
}
