ThreadStaticAttribute in ASP.NET

I have a component that needs to store static values fore each thread. It's a general component that can be used in many scenarios and not only in ASP.NET.

I was thinking to use the [ThreadStatic] attribute to achieve my goal. Supposing that it would also work fine in ASP.NET scenarios, because i was assuming that every Request is called in a own thread.

After some research i found this Blog Post from Scott Hanselman saying to be careful when using [ThreadStatic] in ASP.NET.

However most of the comments (below the Post) do not agree with that was Scott wrote, saying that a Request always run in one thread and that the thread is not used by another request at the same time. That's also what I believe but would love to have some opinion about you experts in here.
