What is ASP.Net? : application codes,pages process,protocol in use..,

ASP.Net is a web development platform,

which provides a programming model, a comprehensive software infrastructure and various services required to build up robust web application

for PC, as well as mobile devices.

ASP.Net works on top of the HTTP protocol and uses the HTTP commands and policies to set a browser-to-server two-way communication and cooperation.

The ASP.Net application codes could be written in either of the following languages:

C#

Visual Basic .Net

Jscript

J#

ASP.Net Web Forms Model:

HTTP is a stateless protocol. ASP.Net framework helps in storing the information regarding the state of the application, which consists of:

Page state

Session state


Page state

The page state is the state of the client, i.e., the content of various input fields in the web form.


Session state

The session state is the collective obtained from various pages the user visited and worked with,

i.e., the overall session state. To clear the concept, let us take up an example of a shopping cart as follows.

User adds items to a shopping cart. Items are selected from a page, say the items page, and the total collected items and price are shown in a different page, say the cart page

ASP.Net session state and server side infrastructure keeps track of the information collected globally over a session.



Server side counterparts of almost all HTML elements or tags, like

and .

Server controls, which help in developing complex user-interface for example the Calendar control or the Gridview control.

The .Net framework is made of an object-oriented hierarchy.

An ASP.Net web application is made of pages. When a user requests an ASP.Net page, the IIS delegates the processing of the page to the ASP.Net runtime system.
