In my Global.asax file I have a Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs) which "should" capture all errors experienced by the application (correct me if I'm wrong here).
My question is, I've seen errors recorded which apparently did not "fail" in terms of my users seeing the custom error page. So what would tell me, if anything, whether or not the type of exception actually caused the custom error page to show.
I want to get better at error handling and looking for any insight or ways to improve the user's experience. Thanks!
