Question about static Objects .net

Question

Are static variable values the same within one session or are their values the same at application server level?

Answer 1

They're at an AppDomain level - that's the same for all static variables, whether they're in ASP.NET or not.

So:

• If you use the same class from different AppDomains, you'll get separate variables
• If your AppDomain is recycled, you'll get separate variables
• If two requests go to different machines, you'll get separate variables
• If two concurrent requests hit the same AppDomain, they can mess with each other (so things like count++ aren't safe)
