Question
QUESTION: Hello,
Where do I define or initialize a session variable, or any other global variable for that matter in an asp.net project? In ASP there was a global.asa page there by default. I don't know what's used in ASP.Net. Could you please help? Thank you SO much!

QUESTION: Thank you. I found that I can add a global application class called global.asax. What's the difference between web.config and global.asax? Which one do you suggest I use for storing session variables, connection strings , and any other global variable? Thanks again!!! :-)

Answer
Hi,

You set all your connection and other constant variables in web.config, all session settings  you can use global.asax.

web.config is an xml configuration file that the application loads when it starts.

global.asax is a class file, it holds the Global application class and its intrinsic methods (e.g., Application_Start ,etc) plus whatever other fields
and methods you want to add there.
