{
   RequestCachePolicy^ policy = gcnew RequestCachePolicy( RequestCacheLevel::NoCacheNoStore );
   WebRequest^ request = WebRequest::Create( uri );
   request->CachePolicy = policy;
   WebResponse^ response = request->GetResponse();
   Console::WriteLine( L"Policy is {0}.", policy );
   Console::WriteLine( L"Is the response from the cache? {0}", response->IsFromCache );
   return response;
}
public static WebResponse GetResponseFromServer(Uri uri)
{
     RequestCachePolicy policy = 
        new  RequestCachePolicy( RequestCacheLevel.NoCacheNoStore);
    WebRequest request = WebRequest.Create(uri);
    request.CachePolicy = policy;
    WebResponse response = request.GetResponse();
    Console.WriteLine("Policy is {0}.", policy.ToString());
    Console.WriteLine("Is the response from the cache? {0}", response.IsFromCache);  
    return response;
