public:
 property System::Net::Cache::HttpRequestCacheLevel Level { System::Net::Cache::HttpRequestCacheLevel get(); };

public System.Net.Cache.HttpRequestCacheLevel Level { get; }

member this.Level : System.Net.Cache.HttpRequestCacheLevel

Public ReadOnly Property Level As HttpRequestCacheLevel

Property Value

A HttpRequestCacheLevel value that specifies the cache behavior for resources that were obtained using HttpWebRequest objects.

Examples

The following code example demonstrates displaying the value of this property.

static WebResponse^ GetResponseUsingCacheDefault( Uri^ uri )
{
   // Set  the default cache policy level for the "http:" scheme.
   RequestCachePolicy^ policy = gcnew RequestCachePolicy;

   // Create the request.
   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 GetResponseUsingCacheDefault(Uri uri)
{
    // Set  the default cache policy level for the "http:" scheme.
    RequestCachePolicy policy = new RequestCachePolicy();
    // Create the request.
    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

Applications typically use Default as their cache policy level. The CachePolicy property, if not null, determines the cache policy in effect for a request. The default policy for the application domain can be set using the DefaultCachePolicy property or by settings in the machine or application configuration files. For more information, see <requestCaching> Element (Network Settings).
