15.4. Summary
In this chapter, you learned how to build an ASP.NET RSS and Atom aggregator. You built a three-pane HTML page to serve as the UI for the application and styled it with CSS; then you built the client-side application to dynamically resize the UI, to request feeds with XParser from the server application, and to use the data to populate the feeds, items, and reading panes.
You learned that while the client-side components of a web application are a necessity to properly display data to the user, server-side components are needed to retrieve the necessary data. Using C# and the .NET Framework, you learned how to retrieve remote XML feeds, cache them, and output them to a page. You also learned how to set HTTP headers so that browsers will know what to expect, and remote servers will know what is hitting them.
Finally, you learned how to set up the application in IIS and test it to make sure that it was properly installed.
