Author: admin | Posted: 13-06-2010 | Category: ASP.NET(vb.net) & Global.asax

ASP.NET(vb.net) Application_End - Global.asax - Application_End() : The Application_Start and Application_End methods are special methods that do not represent HttpApplication events. ASP.NET calls them once for the lifetime of the application domain, not for each HttpApplication instance.
