By default, Silverlight uses the browser s networking stack (when running inside the browser). This places some limits on what you can do when making HTTP requests from Silverlight, as the browser s stack has limitations, and it sometimes modifies the response before passing it back to your application (particularly in regard to HTTP status codes). In order to support Out Of Browser (OOB) mode, the client networking stack was introduced in Silverlight 3, and you can invoke this networking stack instead to work around the browser s networking stack s limitations. Using this stack enables you to access HTTP headers and cookies, to use HTTP verbs other than GET and PUT, and to obtain the actual HTTP status codes returned from the server. It also provides various other benefits. There are some downsides, however, such as the lack of content caching and authentication support. Simply call the RegisterPrefix method on the WebRequest (or HttpWebRequest) class, passing in a prefix (which can be the scheme, or even a domain) to which future calls will use the given networking stack, and passing in the networking stack that those calls will use (with ClientHttp representing the client networking stack): WebRequest.RegisterPrefix("http://", WebRequestCreator.ClientHttp);

Sockets enable you to communicate bidirectionally with the server (i.e., the client can send messages to the server, and the server can send messages to the client). This is particularly useful when you want the server to send the clients notifications, or if you are writing a chat client, for example. Silverlight supports socket communication (with classes in the System.Net.Sockets namespace for support. For scenarios where you want to broadcast messages to all clients, IP multicasting is also supported. As discussed earlier, you are restricted to only using ports 4502 to 4534 unless you are running in OOB mode with elevated privileges. Sockets are best used in intranet applications (rather than publicfacing applications), as the ports will possibly be blocked behind a firewall. In this case you may be better off using a WCF service using the pollingDuplexHttpBinding binding to implement bidirectional duplex communication with the server.

Although in an ideal world nothing would ever break, sometimes things do go off the rails, and being able to identify the cause (or at least narrow it down) is valuable when the clock is ticking. The Memcached protocol defines a method (conveniently called STATS) for retrieving statistics about the state of the instance; this feature is exposed in the MemcachedClient library via the Stats() method. We will make this modification to the Client class in the MemcachedLib project (Listing 6 11). The results are shown in Figure 6 11. Listing 6 11. Retrieving Statistics from Registered Cache Instances using using using using using System; System.Collections; System.Collections.Generic; System.Text; Memcached.ClientLibrary;

Now let s take a look at the calendar s general options. If the user is logged in, you want to show her the options to create a new entry and to log out. However, if the user is logged out, she should see a link to log in. Perform this check by making the modifications shown in bold to the _adminGeneralOptions() method in the Calendar class: < php class Calendar extends DB_Connect { private $_useDate; private $_m; private $_y; private $_daysInMonth; private $_startDay; public function __construct($dbo=NULL, $useDate=NULL) {...} public function buildCalendar() {...} public function displayForm() {...} public function processForm() {...} public function confirmDelete($id) {...} private function _loadEventData($id=NULL) {...} private function _createEventObj() {...} private function _loadEventById($id) {...} private function _adminGeneralOptions() { /* * If the user is logged in, display admin controls */ if ( isset($_SESSION['user']) ) { return <<<ADMIN_OPTIONS <a href="admin.php" class="admin">+ Add a New Event</a> <form action="assets/inc/process.inc.php" method="post"> <div> <input type="submit" value="Log Out" class="admin" />

This chapter taught you how to use WCF RIA Services to expose data and operations from the server to your client Silverlight application, and how to implement all the server-based requirements associated with doing so (such as handling errors, identifying and handling concurrency violations, and sharing code across tiers). The following chapters will show you how to consume this data and call these operations to create a functional Silverlight application.
