Examples

The following code example creates a policy with Level set to CacheOnly, and uses it to set the cache policy of a WebRequest.

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

public static WebResponse GetResponseFromCache(Uri uri)
{
     RequestCachePolicy policy =
        new  RequestCachePolicy( RequestCacheLevel.CacheOnly);
    WebRequest request = WebRequest.Create(uri);
    request.CachePolicy = policy;
    WebResponse response = request.GetResponse();
    Console.WriteLine("Policy level is {0}.", policy.Level.ToString());
    Console.WriteLine("Is the response from the cache? {0}", response.IsFromCache);
    return response;
}

Remarks

You can specify a default cache policy for your application by using the DefaultCachePolicy property or the application or machine configuration files. For more information, see <requestCaching> Element (Network Settings).

You can specify the cache policy for an individual request by using the CachePolicy property.

Caching for Web services is not supported.
