Questions about Singleton and Global Application Class - ASP.NET/VB.NET?

[person]

Here are my questions:


1. I created a file called Global.asax (Global Application Class). There are

Session_Start method and Application_Start. I added the following code in

Session_Start:


DataAccessLayer.Initialize()


However, which place is better and more efficient Application_Start or Session_Start?


-----------------------------

2. A singleton class called DataAccessLayer in VB.NET. There is initialize()

method, we instantiated the object DataAccessLayer within DataAccessLayer class

while we haven't even reach End Class yet! How can this be? Can you please clarify...
