Virtual functions implement the concept of polymorphism are the same as in C#, except that you use the override keyword with the virtual function implementaion in the child class. The parent class uses the same virtual keyword. Every class that overrides the virtual method will use the override keyword.

class Shape
{
    public virtual void Draw()
    {
        Console.WriteLine("Shape.Draw")    ;
    }
}

class Rectangle : Shape

{
    public override void Draw()
    {
        Console.WriteLine("Rectangle.Draw");
    }
}

we know Http is an state-less protocol which is required for interaction between clinet and server .

so there is an need to remeber state of request raised by an web browser so that
web server can recognize you have already previously visited or not.

There are two types of state management techniques:
a) Client side state management
b) Server - side statemanagement

Using cookies comes under clinet side statemanagement .In HttpResponse we write
Cookie containing sessionId and other information within it.

when a browser made a request to the web server the same cookie is sent to the server where server recognize the session id and get other information stored to it previously.

Cons:
1)Cookie should contain non sensitive data as one can easily read cookies and they result of which your security may be tampered .
2) Cookie should not contain large amount of information as they are sent back and forth with request and response in between client and server which may cause your
Performance degradation

A Partial class is a class that can be split into two or more classes. This means that a class can be physically separated into other parts of the class within the same namespace. All the parts must use the partial keyword. All the other classes should also have the same access modifier. At the compile time, all the partial classes will be treated as a single class. Let us list some advantages of having partial classes.
