Actually I am new to ASP.NET and I came through these concepts.
What is the difference between Application_Start Vs Session_Start?
And also how to know how many users are currently active in our application? Is by using Application_Start or by using Session_Start?
Application_Start executes just once when the application/worker process starts or IIS restarts. You can instantiate application variables, for example.
Session_start executes each time a Session is created, such as to instantiate and manage visitor data.
Application_Start Method is Fired on When the Application Started Application_Start runs once before Files are Processed
Where
Session_Start Method is Fired at the beginning of each session. Session_Start runs at the starts of each unique user session.
