Remember that ASP .NET s configuration is very malleable and that you can choose to let clients see your source code by one of two means . You can remove the source code extension to ASP .NET mappings in IIS . Alternatively, you can write your own source code viewer handlers and declare them in your application s web .config file . These handlers plug into the pipeline by implementing IHttpHandler . The next section describes this key interface .

C# public bool IsNavigationTarget(NavigationContext navigationContext) { string id = navigationContext.Parameters["ID"]; return _currentCustomer.Id.Equals(id); }

Here it is . Shield your eyes while you look at Listing 19-2 (just kidding it s not a very big interface) .

public interface IHttpHandler { void ProcessRequest(HttpContext ctx); bool IsReusable {get;} }

The constructor parameters allow you to specify most of the properties you require for the validator You can then set additional properties, such as the Tag or the resource name and type if you want to use a resource file to provide the message template You can also build combinations of validators using this approach to implement complex validation rules Resolve individual validators through the Enterprise Library Container This approach allows you to obtain a validator instance using dependency injection; for example, by simply specifying the type of validator you require in the constructor of a class that you resolve through the container If you specify a name when you resolve the instance, this is interpreted as the name of the rule set for that validator to use when validating objects.

There s really not much to it, is there The interface includes a method named ProcessRequest and a property named IsReusable . If the handler instance can be used multiple times,

If the IsNavigationTarget method always returns true, regardless of the navigation parameters, that view instance will always be reused This allows you to make sure that only one view of a particular type will be displayed in a particular region Confirming or Canceling Navigation You will often find that you will need to interact with the user during a navigation operation, so that the user can confirm or cancel navigation In many applications, for example, the user might try to navigate while in the middle of entering or editing data In these situations, you may want to ask the user whether he or she wants to save or discard the data that has been entered before navigating away from the page, or whether the user wants to cancel the navigation operation altogether Prism supports these scenarios via the IConfirmNavigationRequest interface.

IsReusable should return true . If the handler generally returns static content, it s probably reusable . If the content is dynamic, it s probably not reusable . The heart of the handler is the ProcessRequest method that includes a single parameter: the current HttpContext . When a request finally arrives at the handler (through the ProcessRequest method), ProcessRequest can literally do anything to respond to the request . The Trace .axd handler responds to a GET request by listing the requests being tracked by the runtime . The forbidden handler responds by tossing a roadblock in the processing pipeline so that the client can t see the forbidden resource . A custom Web service might respond to the request by parsing the XML payload, constructing a call stack, and making a call to an internal method . Implementing IHttpHandler is simple at least from the architectural standpoint . The ProcessRequest method takes a single parameter the current HttpContext . However, the code inside ProcessRequest is free to do just about anything, possibly making the internal processing quite complex! The following example illustrates taking over the entire formrendering process to display a list of choices in a combo box, allowing the end client to select from the choices, and finally rendering the chosen item .

See Appendix A, Dependency Injection with Unity and Appendix B, Using Dependency Injection in Enterprise Library for more information about using a container to resolve and populate the dependencies of objects..
