Page titles are displayed in the title bar of the browser; by default, Drupal displays your site name and slogan on the front page. Search engines use this content for both search rank and when displaying search results, typically as a header that links to your site. The Page Title module (http://drupal.org/project/page_title) gives you precise control over what is displayed in the page title for all areas of your site, including the front page, comments, users, content types, and vocabulary. You can also use tokens to insert field values or other variables. The Page Title module is configured by navigating to content and selecting the PAGE TITLES tab, as shown in Figure A-4.

You can actually skip this step if you are developing with Visual Studio 2005, because it will dynamically generate the proxy class file for you when you add a Web reference (for your Web service) to a client project. However, we prefer to manually generate the proxy class file so that we can either alter it or have it ready for clients who are using a development tool without code-generating wizards.

Up to now, all the examples in this book have been small and to the point, demonstrating one or two particular topics. The examples weren t particularly flashy, but they demonstrated an important piece of the Ajax puzzle. This chapter s example, known as the Ajax Dashboard, is a completely cross-browser application that mimics the Mac OS X Tiger Dashboard feature. While this example isn t nearly as polished as its parent, it does serve as proof that Ajax is easy to use and can provide a huge leap in usability. The Ajax Dashboard also serves as a demonstration test bed for the Taconite framework, so you ll see how much work the Taconite framework can save you. The full source code for the Ajax Dashboard is available from the Source Code section of the Apress Web site (www.apress.com). From there you can download the source and also the prebuilt WAR file that is ready to run in any modern servlet container such as Tomcat.

This final step hooks a client to your Web service. If you are using Visual Studio 2005, simply add a (dynamic) Web reference to the Web service in your client project, and this will automatically generate the proxy class file for you. This wizard will also make the necessary adjustments to your application configuration file to record the location of the Web service. Alternatively, you can manually add the proxy class file from step 5 to your project, update the configuration file, and begin coding. The client essentially does nothing more than delegate method calls to the Web service. Valid clients include Web applications, Windows Forms applications, console applications, or even other Web services.

The Menu Attributes module (http://drupal.org/project/menu_attributes) allows you to add additional attributes to menu items, such as an ID, name, and class. Important to SEO, it allows you to specify rel="nofollow" on certain menu items, telling the search engine not to use the link in determining search rank. For example, you may write a blog post about a specific product, but you don t want to give the site an endorsement. Some sites may use the nofollow attribute to sculpt page rank; see http://mattcutts.com/blog/pagerank-sculpting for details.

Figure 8-7 shows the Ajax Dashboard. It consists of four small windows, each containing a different mini-application. The first window provides a simple seven-day weather forecast for 3565005953993bd3170c41194f12907b any valid U.S. ZIP code by showing the projected high and low temperatures along with the

Note: Page rank sculpting is not generally used on most sites but should be reserved for contentintensive sites with deep links or when a particular word or phrase is extremely competitive.

This process is obviously more involved than simply creating a new .asmx file and immediately implementing code. But it is the right way to do things because it abstracts out the Web service definitions and the code implementations. Visual Studio and the .NET Framework provide all of the tools that you need to autogenerate the XML-based files and the code, so the amount of manual work is kept to a minimum. The rest of this chapter dissects the various moving parts that make up a messageoriented Web service. You will gain a precise understanding of how multiple files and tools work together to define and implement a message-oriented Web service. We will also provide selective implementation examples that collectively show you how to build this type of Web service from scratch.

expected cloud cover for the day. The forecast automatically changes whenever the ZIP code changes, and Ajax automatically refreshes the forecast as long as the window is open within the browser.
