Are Application_Error and Page_Error triggered by the same event?

[Matt]

As the subject says... are Application_Error and Page_Error triggered by the
same event? In other words, is there any error that could slip by
Application_Error but be caught by Page_Error, or vise-versa? Or is it just
a matter of handling the same exact thing in different scopes?

If Page_Error does not clear the error, then Application_Error will get
called. So Page_Error is kind of like a first line of defense. If it doesn't
deal with the error, it will go to Application_Error.

But, is there any situation where having a Page_Error function will catch
errors that an Application_Error would not catch?
