I have a question about the ASP.NET architecture and how
classes are instantiated.

When a web page invokes a static class and the class uses
some static storage within the class, does the static
storage exist beyond the invocation of the web page? Is
the static storage global and available to all threads
that might invoke the static class?

Static classes are stored in the application heap, which means that values
in a static class are persistent for the lifetime of the application and are
accessible to all objects in the application. Static classes are not
instantiated, meaning that there is only one copy of the class.

Beware of the dreadful process recycling feature of ASP.net though... (see
machine.config / search for "ProcessModel")

Thanks for the replies. Yes, I do understand the process
recyling issues. However, except for out of process or
database based session state, does not process recycling
affect everything the same way (i.e. application state,
cache, static objects and storage, etc)? If the process
recycles, everything is wiped! Correct??

Wen an Application Pool is recycled, yes, all process memory is wiped clean.
