| A Dot Net Guruer of Context |
| MSDN |
| ASP introduced several intrinsic objects like Request and Application to help track the context for an HTTP request. ASP.NET takes the next step and bundles these objects, plus several additional context-related objects into an extremely handy intrinsic object called Context. Context is an object of type System.Web.HttpContext. It is exposed as a property of the ASP.NET Page class. It's also available from user controls and your business objects (more on that later). |

| An Introductory Guide to Building and Deploying More Secure Sites with ASP.NET and IIS |
| MSDN |
| ASP.NET and Microsoft Internet Information Services (IIS) work together to make building secure Web sites a breeze. But to do it right, you have to know how the two interrelate and what options they provide for securing access to a Web site's resources. This article, the first in a two-part series, explains the ABCs of Web security as seen through the eyes of ASP.NET and includes a hands-on tutorial demonstrating Windows authentication and ACL authorizations. A range of security measures and authentication methods are discussed, including basic authentication, digest authentication, and role-based security. |

| An Introductory Guide to Building and Deploying More Secure Sites with ASP.NET and IIS, Part 2 |
| MSDN |
| Forms authentication is one of the most compelling and useful new features of ASP.NET. It enables developers to declaratively specify which files on their site can be accessed and by whom, and allows identification of a login page. When an unauthenticated user attempts to retrieve a page protected by forms authentication, ASP.NET automatically redirects them to the login page and asks them to identify themselves. Included here is an overview of forms authentication and what you need to know to put it to work. Also included is hard-to-find information on the security of cookie authentication and on combining forms authentication with role-based URL authorizations. |

| Application of the Cache Subsystem for Web Applications |
| C#Today |
| In this article, Eric Rhea explores two approaches to utilizing the caching system. First, he talks about how to make use of the cache subsystem from the web-form code. Then, he takes a look at exploring how to make use of the cache subsystem in the code behind. While doing this, he seeks three answers: (1) how to improve performance, (2) how to make use of similar techniques in both code areas, and (3) how to cache an object which is indeterminate in length and whose values you do not know in advance, and one which you cannot cache using the web-form directive. |

| Bugslayer: Handling Assertions in ASP .NET Web Apps |
| MSDN |
| Recently I was moving along with my ASP .NET Web site de-sign and was quite pleased to see just how much easier ASP .NET made the whole process. Being a good boy, I went through the design process and was about to start development when I noticed a small problem. A prototype I developed to test a theory would hang when I used the standard Debug.Assert. |

| Build an XML Serialized Object |
| Visual Studio Magazine |
| Almost every Web application needs to store global configuration settings. Traditional Active Server Pages (ASP) Web applications often stored this data in a database. However, database storage has drawbacks: It's terribly inefficient to query the database each time you need to retrieve a setting, and some data, such as your database connection string, isn't appropriate for storage in a database. Many developers try to get around these two caveats by storing settings in Application variables initialized in the global.asa file. The problem with this approach is that changing the value of one of these Application variables in the global.asa file forces the entire ASP application to reload, leading to periods of downtime. |

| Creating HttpHandlers and HttpModules |
| Bipin Joshi |
| Http handlers are special applications that typically handle files with certain extension. For example when you request a file with extension .asp IIS routes it to ASP processor. But what if I want to handle files with my own extensions say .bipin? Http handlers allow us to do just that. Now, you might be thinking what is the use of a new file extension? Consider a case where you want to generate graphics on the fly. In such cases you will write an Http handler that will do your task. Note that Http handlers are typically called for the specific file extensions they are designed for. If you have worked with ISAPI extensions in past you will find this concept very familiar. |
