One of the most sure-fire ways to improve a web application's performance is to employ caching. Caching takes some expensive operation and stores its results in a quickly accessible location. ASP.NET version 1.0 introduced two flavors of caching:

• Output Caching - caches the entire rendered markup of an ASP.NET web page or User Control for a specified duration.
• Data Caching - a programmatically-accessible, in-memory data cache for storing objects in the web server's memory.

For a more in-depth discussion on ASP.NET 1.x's caching capabilities, refer to Scott McFarland's Caching with ASP.NET and Steve Smith's ASP.NET Caching: Techniques and Best Practices articles.

In ASP.NET 2.0, the caching system has been extended to include SQL cache dependencies, cache profiles, and post-cache substitution for output cached pages. The Caching for Performance section of the ASP.NET 2.0 QuickStarts provides a good overview of ASP.NET 2.0's caching options. This article explores output caching in ASP.NET 2.0, starting with an overview of output caching and followed by a detailed look at creating pages that include both cached and non-cached markup using fragment caching and post-cache substitution techniques.

As the attacks in which hackers use become more and more sophisticated, and the programs in which they attack become increasingly complex, encryption is becoming the last line of defense in database management system (DBMS) security.

In this article we will look at how, specifically, to encrypt the data in a SQL Server 2005 database using symmetric encryption techniques. We'll start with examining the facilities for managing keys in SQL Server and then explore symmetric encryption in SQL Server 2005.

Excel services is yet another important pillar in Microsoft’s business intelligence offering. Business users really like Excel because it is easy to use and they can add complex formulas to Excel to express their logic.They can do so without involving the IT guy. The problem with this scenario, however, is that it becomes very difficult to share some Excel sheets with their coworkers. Usually users prefer to send workbooks via email, but sometimes the workbooks are too large for email, sometimes they have backend data connections, and sometimes workbooks send via email cause version confusion hell.

In this article we will see just how easy it is to display XML data in an ASP.NET 2.0 page. In particular, we will build a User Control that will display the contents of an RSS feed. Once created, this User Control can be dragged onto the Design surface of any ASP.NET page in your project and configured to display the contents of a particular RSS feed by simply setting the control's Url property to the URL of the RSS feed.
