JavaScript: ASP.NET Session Management

ASP.NET Session Management

1.Why is http protocol stateless ?

Http is called as a stateless protocol because each request sends without any knowledge of that request.
means once the request sends to the server after responding to that request, the server lost that connection.

In our application, I go to the HomeController and in that First, I sends the request to the index. So let's see:

Here I create a variable that is i=0 and increment that as an i++. And I also put the debug point when I run this first GET request is sent. now we see:

Now the i value is incremented here i=1. After that server responds and then end-user see the application. Now If the end-user again sends the request from the same browser. This is the second request. Now see what will happen:

See here the i becomes 0 again. This is the HTTP stateless protocol.
