I am fairly new to ASP.NET and am trying to understand some code I am responsible for.
There are many references to Request("id") and also Request("ID") in this project. I understand that Request is the current System.Web.HttpRequest, but I don't understand what Request("id") is although I can see that refers it holds the id of different controls on the corresponding html.
1. Are Request("id") and Request("ID") the same thing? What do the values mean?
2. Are they a piece of ASP.NET or are they something in my project somewhere?
3. What would it mean for Request("id") to be nothing?
