Automatically Add Headers and Footers to Every Page Using ASP.NET - Part 2
Reader Level:

Say it with me - "No more cloning!" That's right, you can add the same header and footer to every page in your ASP.NET website by modifying just the Global.asax. This article is the second in a series. You'll learn how to create a custom filter, which is used to insert the header and footer text in every .aspx page. This technique is better than the one described in Part 1 in that each page retains its own distinctive head section. And as an added bonus, you'll learn about a handy C# concept called verbatim literal strings.

Protect .zip and .exe Files on Your Server Using an HttpHandler - Part 2
Reader Level:

Forms authentication is a clever way to protect resources within specified folders of your web site. The problem is, by default only ASP.NET resources (e.g., .aspx, .asmx, .ascx, .asax, .config files plus a couple others) are protected. But what if you have .zip files or .exe files in those folders as well? If not explicitly protected, users who know the location and name of the .exe or .zip file can simply browse to the file and download it from your server. Not a happy situation. Fortunately, there's a solution. In this two-part article, you'll learn how to protect non-ASP.NET resources. By the end of Part 2, you should be able to extend the paradigm to protect other types of files as well.
