The life span of a variable is as long as the class instance it is
associated with, and the object will live for as long as you hold a
reference to the object. We typically don't hold a reference to a Page
object since they are only used to process a single request. You could
put an object reference inside the Session, Cache, or Application
objects to keep the object around a bit longer.

You can also mark a field as static (shared in VB.NET) and the field
will be around for the duration of the application. A static field
also means there is only one instance of the field in the entire
application - no matter how many objects get created - so you have to
be sure this is what your design really calls for. Globals like this
are a double edged sword.
