Why does my ASP.Net static function's “context” crossover between user sessions?

Question

I think I need some help understanding how static objects persist in an ASP.Net application. I have this scenario:

someFile.cs in a class library:

p

Static data is shared among the entire application domain of your webapp. In short, it's shared among all the threads serving requests in your webapp, it's not bound to a session/thread/user in any way but to the webapp as a whole.(unlike e.g. php where each request lives in its own isolated environment bar a few knobs provided - such as the session variable.)
