Abstract

This time I've found another victim: ASP.NET. It is a pre-compiled language running on web-servers like IIS. I want to explain 'pre-compiled' a little bit: The server, when it runs a specific file for the first time, compiles it for execution (not as i.E. PHP, which are just interpreted) and saves the compiled version of the file. The advantage: The next executions are a lot faster than at pre-processor languages like PHP. The advantage in contrast to ASP is that we can use the whole amount of functions, methods, classes provided by the .NET Framework. ASP.NET scripts can be written in VB.NET, C#, C++ and J#. I've desided to use VB.NET for this article. For the codes I've used .NET Framework 1.1 and 2.0 beta (at IIS), and the codes run at both environment. Well, now let's look at the ASP.NET infection :)
