It is always good to know and master the environment you work in. Usually you need to keep track of the current ”request headers”, ”environment variables”, ”server variables” and ”session variables. In php you could use the phpinfo() function to check your installation. However, I do not know about any equivalent in .NET.
On this page you can find an application that give you some of these variables. But I wanted a C# version which displays some more information as well. Therefore I made my own small version. Unfortunately I have no online .NET server and can’t provide a demo (help someone?)
You can download the application source code here: aspnetinfo.zip
Feel free to customize the application for your need. If you make a superior version, then put it on the web and tell me about it.
