WebPages Global

This lesson is part of ASP · All levels

Summary

Global files like Global.asa allow you to run code at critical moments in the application lifecycle, such as when an application starts, a session is created, or an application ends. So a joint initialisation like setting up a connection or global variable only needs to be done once. Understanding this lifecycle is important so that the application does not repeat the same job on every request.

Key points

It hosts events such as Application_OnStart, Application_OnEnd, Session_OnStart, and Session_OnEnd.
The application is valid for all users, while the session is for one visitor only.
Event Application_OnStart runs once when the app is first accessed.
Initiation codes should be placed on the startup event, not on every page.
