Get Started with a Windows Server AppFabric Cache Client

Windows Server AppFabric offers the option to configure the cache client programmatically or with an application configuration file. The following procedures describe how to programmatically configure a cache client used by your application. For information about how to do this with an application configuration file, see Get Started with a Windows Server AppFabric Cache Client (XML).

To programmatically configure your cache client, create an instance of the DataCacheFactoryConfiguration class to specify configuration settings. Then pass this object to the DataCacheFactory class constructor.

TipTip
For performance reasons, we recommend that you minimize the number of DataCacheFactory objects created in a cache-enabled application. Store the DataCacheFactory object in a variable available to all parts of the application that use cache clients.

noteNote
These procedures assume that you have already prepared your development environment to use the Cache Client features. For more information, see Preparing the Cache Client Development Environment (Windows Server AppFabric Caching).

To configure a cache client programmatically

  1. Create an array of DataCacheServerEndpoint objects to specify the cache hosts for the client.

  2. Create an instance of the DataCacheFactoryConfiguration class.

  3. Configure your cache hosts by assigning the cache host array from the first step to the Servers property of the DataCacheFactoryConfiguration object.

  4. Pass the DataCacheFactoryConfiguration object to the constructor of the DataCacheFactory class.

  5. Use the GetDefaultCache method or the GetCache method to obtain a DataCache class based on the settings of the DataCacheFactoryConfiguration object.

Example

This example shows the programmatic configuration of a cache client for a cache named NamedCache1. This cache client has local cache disabled and is configured to point to a cache server that is named CacheServer2. To use this example in your own application, replace the server properties in this example with those of your cache server(s). Add additional DataCacheServerEndpoint objects to the servers array for each of the other cache hosts in the cluster.

Specify those cache hosts that have been designated lead hosts. Lead hosts are usually the first cache servers installed in the cluster. For more information about lead hosts, see Windows Server AppFabric Caching Physical Architecture Diagram. You can determine which hosts are lead hosts by using the Windows PowerShell administration tool. For more information about Windows PowerShell, see Using Windows PowerShell to Manage Windows Server AppFabric Caching Features.

First the servers array is created. This example configures a cache host that is named CacheServer2.

// Declare array for cache host(s).
DataCacheServerEndpoint[] servers = new DataCacheServerEndpoint[1];
servers[0] = new DataCacheServerEndpoint("CacheServer2", 22233);

Next create a DataCacheFactoryConfiguration object. Assign the servers array to the Servers property.

// Setup the DataCacheFactory configuration.
DataCacheFactoryConfiguration factoryConfig = new DataCacheFactoryConfiguration();
factoryConfig.Servers = servers;

Next, pass the DataCacheFactoryConfiguration object to the DataCacheFactory class constructor and instantiate the cache client with the GetCache method. This example creates a cache client for a cache that is named NamedCache1.

// Create a configured DataCacheFactory object.
DataCacheFactory mycacheFactory = new DataCacheFactory(factoryConfig);

// Get a cache client for the cache "NamedCache1".
DataCache myDefaultCache = mycacheFactory.GetCache("NamedCache1");
