About ASP

ASP is a server side scripting technology that enables scripts to be executed by an Internet server.

	ASP is a Microsoft Technology
	ASP stands for Active Server Pages
	ASP is a program that runs inside IIS
	IIS stands for Internet Information Services
	IIS comes as a free component with Windows 2000
	IIS is also a part of the Windows NT 4.0 Option Pack
	The Option Pack can be downloaded from Microsoft
	PWS is a smaller - but fully functional - version of IIS
	PWS can be found on your Windows 95/98 CD

What is an ASP File?

	An ASP file is just the same as an HTML file
	An ASP file can contain text, HTML, XML, and scripts
	Scripts in an ASP file are executed on the server
	An ASP file has the file extension ".asp"

How does it Work?

	When a browser requests an HTML file, the server returns the file
	When a browser requests an ASP file, IIS passes the request to the ASP engine on the server
	The ASP engine reads the file, line by line, and executes the scripts in the file
	Finally, the ASP file is returned to the browser as plain HTML

What is ASP+?

	ASP+ is the same as ASP.NET.
	ASP+ is just an early name used by Microsoft when they developed ASP.NET.

What is ASP.NET?

	ASP 3.0 is the latest version of ASP, but there will never be an ASP 4.0 version.
	ASP.NET is the next generation ASP, but it's not an upgraded version of ASP. ASP.NET is an entirely new paradigm for server-side ASP scripting.
	ASP.NET is a part of the .NET Framework. Microsoft spent three years rewriting ASP.NET from the ground up, and ASP.NET is not fully backward compatible with ASP 3.0.
	You can read more about the differences between ASP and ASP.NET in the next chapter of this tutorial.

Differences between ASP and ASP.NET ?

	ASP. net supports object oriented techniques.
	ASP.net is compiled, rather than interpreted, so overall performance of asp.net application is much better.
	ASP.net supports two new mode of authentication, form based and passport based authentication
	ASP.net supports ADO.net.
	New features such as :

                  a. Smart Navigation
                  b. AutoPost Back
                  c. View state management.
                  d. Advanced web controls such as datagrid, validating controls, etc

	Supports more than one language for programming business logic. (C#, VB, etc)
	ASP.net provide RAD Tool, thus development becomes faster.

.NET Framework

	The .NET Framework is the infrastructure for the Microsoft .NET platform.
	The .NET Framework is an environment for building, deploying, and running Web applications and Web Services.
	The .NET Framework contains a common language runtime and common class libraries - like ADO.NET, ASP.NET and Windows Forms - to provide advanced standard services that can be integrated into a variety of computer systems.
	The .NET Framework provides a feature-rich application environment, simplified development and easy integration between a number of different development languages.
	The .NET Framework is language neutral. Currently it supports C++, C#, Visual Basic, and JScript (Microsoft's version of JavaScript).
	Microsoft's Visual Studio.NET is a common development environment for the .NET Framework.

	ASP .NET has better language support, a large set of new controls and XML based components, and better user authentication.
	ASP .NET provides increased performance by running compiled code.
	ASP .NET code is not fully backward compatible with ASP.

New in ASP .NET

	Better language support
	Programmable controls
	Event-driven programming
	XML-based components
	User authentication, with accounts and roles
	Higher scalability
	Increased performance - Compiled code
	Easier configuration and deployment
	Not fully ASP compatible

Language Support

	ASP .NET uses the new ADO .NET.
	ASP .NET supports full Visual Basic, not VBScript.
	ASP .NET supports C# (C sharp) and C++.
	ASP .NET supports JScript as before.

ASP .NET Controls

	ASP .NET contains a large set of HTML controls. Almost all HTML elements on a page can be defined as ASP .NET control objects that can be controlled by scripts.
	ASP .NET also contains a new set of object oriented input controls, like programmable list boxes and validation controls.
	A new data grid control supports sorting, data paging, and everything you expect from a dataset control.

Event Aware Controls

	All ASP .NET objects on a Web page can expose events that can be processed by ASP .NET code.
	Load, Click and Change events handled by code makes coding much simpler and much better organized.

ASP .NET Components

ASP .NET components are heavily based on XML. Like the new AD Rotator, that uses XML to store advertisement information and configuration.

User Authentication

ASP .NET supports forms-based user authentication, including cookie management and automatic redirecting of unauthorized logins.

(You can still do your custom login page and custom user checking).

User Accounts and Roles

ASP .NET allows for user accounts and roles, to give each user (with a given role) access to different server code and executables.

High Scalability

	Much has been done with ASP .NET to provide greater scalability.
	Server to server communication has been greatly enhanced, making it possible to scale an application over several servers. One example of this is the ability to run XML parsers, XSL transformations and even resource hungry session objects on other servers.

Compiled Code

The first request for an ASP .NET page on the server will compile the ASP .NET code and keep a cached copy in memory. The result of this is greatly increased performance.

Easy Configuration

	Configuration of ASP .NET is done with plain text files.
	Configuration files can be uploaded or changed while the application is running. No need to restart the server. No more metabase or registry puzzle.

Easy Deployment

No more server restart to deploy or replace compiled code. ASP .NET simply redirects all new requests to the new code.

Compatibility

	ASP .NET is not fully compatible with earlier versions of ASP, so most of the old ASP code will need some changes to run under ASP .NET.
	To overcome this problem, ASP .NET uses a new file extension ".aspx". This will make ASP .NET applications able to run side by side with standard ASP applications on the same server.

What You Need ?

A Windows Computer

ASP.NET is a Microsoft technology. To run ASP.NET you need a computer capable of running Windows.

Windows 2000 or XP

If you are serious about developing ASP.NET applications you should install Windows 2000 Professional or Windows XP Professional.

In both cases, make sure you install the Internet Information Services (IIS) from the Add/Remove Windows components dialog.

Service Packs and Updates

Before ASP.NET can be installed on your computer, it is necessary to have all relevant service packs and security updates installed.

The easiest way to do this is to activate your Windows Internet Update. When you access the Windows Update page, you will be instructed to install the latest service packs and all critical security updates. For Windows 2000, make sure you install Service Pack 2. I will also recommend that you install Internet Explorer 6.

Remove Your Beta Version

If you have a Beta version of ASP.NET installed, we recommend that you completely uninstall it. Or even better: start with a fresh Windows 2000 or XP installation.

Install .NET

	From your Windows Update you can now select to install the Microsoft .NET Framework.
	After download, the .NET framework will install itself on your computer - there are no options to select for installation.
	You should now be ready to develop your first ASP.NET application!

The .NET Software Development Kit

	If you have the necessary bandwidth to download over 130 MB, you might consider downloading the full Microsoft .NET Software Development Kit (SDK).
	We fully recommend getting the SDK for learning more about .NET and for the documentation, samples, and tools included.
