ASP is known as Active Server Pages which is produced by Microsoft Team in the early of year 1990. Microsoft Active Server Pages (ASP) is allowed us to build dynamic and interactive web applications. ASP classic is easily to let web application link to database inside the web application. The web application created by ASP does not affect by using different type of the web browser. The file extension for ASP is .asp. Example:

The default programming language to build ASP web site is using VBscript to buid, but it is support other programming languages like JSscript (JavaScript from Microsoft). But allows web developer use either visual basic (VB) or language to build the web applications.

Compilation Process

There are 2 type of compilation that available which is pre-compiled code and interpreted code.

Pre-compiled code

Pre-compiled code is compiled when the web developers are done writing it and well before started to use it. Pre-compiled code only requires compiling once. So, the performance is much faster. Pre-compiled is Machine dependence.

Interpreted Code

Interpreted Code compilation process is totally different from Pre-compiled code. Interpreted code is only compiled at the times of its execution which mean when the user requests the page. Interpreted code compilation will only compiled the code when there is any request from the user. So, the performance will slower than Pre-compiled code. Interpreted code is machine independence.

.Net solves the problem by using a two-step process for compilation

The 2 step of the compilation is common intermediate language (CIL) and common language runtime (CLR). .Net is compiled all the code to CIL. Then change it to become machine independent language (CLR).

The CLR is responsible for executing your application code. When the web developers write an application for the .NET Framework with a language such as VB .NET or C#, the source code is never compiled directly into machine code. Instead, the VB or C# compiler converts your code into a special language named as MSIL (Microsoft Intermediate Language) or CIL (Common Intermediate Language).

MSIL looks very much like an object-oriented assembly language. However, unlike a typical assembly language, it is not CPU specific. MSIL is a low-level and platform-independent language. When the web application actually executes, the MSIL code is "just-in-time" compiled into machine code by the JITTER (the Just-In-Time compiler).

The entire web application is not compiled from MSIL into machine code. Instead, only the methods that are actually called during execution are compiled. In reality, the .NET Framework understands only one language: MSIL or CIL. However, the web developers can write applications using languages such as Visual Basic .NET and C# for the .NET FrameworkBecause the .NET Framework includes compilers for these languages that enable you to compile your code into MSIL.You can write code for the .NET Framework using any one of dozens of different languages, including Ada, Apl, Caml, COBOL, Eiffel, Forth, Fortran, JavaScrip, Oberon, PERL, Pascal, PHP, Python, RPG, Scheme, Small Talk

Below the diagram is to explain how the CIL and CLR work in the .Net framework.

First of all, the web developers using different type of programming languages to write their web application. After that, the code is compiled using their own compiler to convert into Common Language Infrastructure. .Net compatible language compile to a second platform-neutral language called Common Immediate Language (CIL). After the Common Language Runtime compiles the CIL to machine readable code that can be executed on the current platform.

What is Web server?

Web servers are software that manage web pages and make them available to client browsers - via a local network or over the Internet (two different machines or same machine).While there are many Web servers available (the common ones being Apache, Internet Information Services (IIS), and iplanet Enterprise Server)

To test or run ASP.NET Web applications, you need a Web server

Internet Information Services (IIS)

IIS Web server comes bundled with Windows 2000, Windows XP Professional, and Windows Server 2003.

This Essay is

a Student's Work

Lady Using Tablet

This essay has been submitted by a student. This is not an example of the work written by our professional essay writers.

Examples of our work

An ASP page is stored at server-side. So, client cannot simply view an ASP page on the web browser. They need to request the ASP page through the web server which is supports for ASP. When a client request an ASP page through the web browser, the web server will locates the ASP file on the hard drive and interpret it. After that, it will remove all the ASP Script and replace them with HTML Text. Below is the diagram:

(picture 1)

This is the ASP script for a page called 'HelloWord.asp'

Web server locates the ASP file and replace with HTML text and send back to the web browser.

Problem with ASP Classic

ASP is using html controls to interact with the user. Although ASP is having few good functions to build web application, it still not perfect yet to satisfy web developer in some of the areas. For example, ASP needs to code all the things in a single web page including the functions and interface. It is not very convenience when need to modify or update some of the data on the web page.

Besides that, another disadvantages using ASP classic to build web page is lack of the performance and scalability, which means the web page that built by ASP classic will not auto fix the web pages with the web browser. The layout of the web page will out of the margin and the content cannot show as what web developer have designed for.

How does work?

Think of ASP.NET pages as normal HTML pages that have sections marked up for special consideration. When .NET is installed, the local IIS Web server is automatically configured to look out for files with the extension ASPX and to use the ASP.NET module (a file called aspnet_isapi.dll) to handle them.

First of all, the client requests the web page from the web server. Then the web server started to locates the instruction file. Meanwhile, the code is sent to the Common Language Runtime for compilation. After that, the HTML stream returned to the web browser. After the web browser get the HTML code. It will processes the HTML code and display the content of the page to the client.

ASP.NET compared with ASP Classic

Now, I will differentiate the asp version between and ASP classic. What are the changes in instead of the ASP classic and what is the improvement from ASP classic. Besides, I am also focus on what are the new features in

First of all, the mainly difference from ASP classic is is is support more language for scripting. For example, supports visual basic language, C#, C++, Jscript and as well. Support multiple languages will getting more web developer choose as their first choice to develop a web page and web applications and let different background programmer can work together by using a same application.

Besides, there are few points to compare between and ASP classic. One of the aspects is compilation. ASP classic is built up by Jscript and it only interpreted the Script line by line when the page is requested. Moreover, compilation is totally different with ASP classic. is automatically compiling all the code while the code is first time executed. The compiled code will store inside .NET classes within assembly. .NET classes are including the server-side coding and HTML code. So, when ASP.NET page is executed for first time, the compiled code will store inside the .NET classes. Next time will render the page by execute the compiled code that has created. The performance for will be increased because there are no longer like the ASP classic has the difference between the compiled code and the coding within the server-side languages within asp web page. performance is faster due to the compiled code but ASP classic is using the scripting languages like VBScript. VBScript is representing to machine code and did not require any additional parsing. That is why web developer is preferred to use instead of using ASP classic.

On the other hand, the difference between and ASP classic is the scalability factor. For ASP classic, the components inside the web pages are not easy to update, replace and maintain it. If want to update particular component, IIS is required to shut down then only can successfully replace or update the component. After done all the modification, IIS need to restart once.( Neel Sus. 2009).

For, it was different with ASP classic which it is scalable and easy to do modification on the web pages. The term of 'Xcopy' command is used to build an efficiency web application page. The 'Xcopy' term is to copy a file to another location. It is allow to do the modification without need of restart of web server. The web developer can do the changes on the web application and no web server restart is required to take effect. It will direct take effect once the web application is requested.(Bean Software. 2002).

Advantages of using ASP.NET

After compared the version between and ASP classic, here is some of the advantages of using has reduced the need of code to build a web application; it required lesser code to build a large web application. This will help web developer save time, and more efficiency to build a large web application.

Another new feature from which does not include in ASP classic is the authentication function. Authentication is the processes to obtain and validate the information that provide by user are valid or not. If it is valid, the user will get the authorization and the authorization process will check the user whether have permission to access the particular resources on the web pages. It will increase the security of the web application and make sure all the user information is secured and not grab by someone. (MSDN. 2010).

Besides that, file extension is '.aspx' and it has a code behind page which is '.aspx.cs'. The difference between .aspx and .aspx.cs is .aspx is the interface for the web application. It stored all the html coding and some of the C# language label for some of the particular components. Meanwhile, 'aspx.cs' is a place to let web developer to code all the functionality for the button, and the business logic on that page.

Moreover, is server-side technology which means all coding is executed and compiled on the server side before it send it back to the web browser. Below is the example of code behind on 'aspx.cs':

The ASP classic need to code a web application coding inside a same page including the HTML and the function code. It will become messy if web develop wanted to do the modification on the web pages. It need take some time to analyze the code first before doing any modification. (Steve Kozyk. 2008).

The disadvantages of using ASP.NET

One of the main disadvantages of using application is it only support on Windows platform. That means other based Operating System is not allowed to use to develop their web application. The limitation of the will make some of the web developer abandon to use to develop their web application and choose other more appropriate application to develop their web application such as PHP support in any platforms. 1.x compared with 2.0

We move to the next topic which is the comparison between 1.x and 2.0. 1.x release on year 2002-2003 and 2.0 is released on year 2005.

Firstly, we compared the compilation models for this 2 version. 1.x will only automatically compile few files such as asp page (.aspx), user control, http handler, web services and Global.asax class files. Others file that not automatically compile, web developer need to compile the rest of the files before publish the web application to the web server. 2.0 has increase the efficiency in the compilation process. 2.0 will automatically compile the file types that include asp page file (.aspx), asp and asp page behind code (.cs). So, the web developer only need to create the web application and publish it. 2.0 have a folder called App_Code which can keep the helper classes, business object inside but cannot put the asp pages (.aspx), Global.asax and other non-code files. 2.0 will compile elements inside the App_Code folder and name as code.dll.

In 1.x, when the web developer need to do the modification on the web application, they need to open the entire project file do modify and update it. After done the modification, they need to compile the entire project and publish it to web server again. But 2.0 allows web developer just open the particular file that wants to modify. After done the modification, web developer just need to publish the file code to the web server and no need to recompile.

In 1.x, the code behind page of web application are require an IIS virtual directory to run and the IIS is require to store inside the local computer which used to develop the web application. 2.0 code behind page can access the local host IIS directly and the IIS has store inside the web server.

In 1.x, the procedure to process the web application page is send the client request to the web server. First, the Init event is called. After that, called the Load event by the PreRender event is called net. Lastly, the Unload event is called and the generate output will sent it back to the client.

In 2.0 has added few new attributes. The attributes will help web developers to have a control for the new framework features which is theming and personalization. Besides, 2.0 Page class has provided new method, event, and properties. The 3 important script for the properties is ClientScript, Header.IPageHeader and Master. There are 3 new important methods such as GetValidators, setFocus, and RegisterRequiresControlState.

In 2.0, there are few new events implements. First, PreInit is called before initial the web page. Then, InitComplete will be occur when the page is completely initial. Next, the PreLoad event is called immediately after the InitComplete event and before the web page begin to load. The LoadComplete event will occur after the page is load complete at the end. Last, PreRenderComplete event is occur and this event will store personalize data and page HTML is rendered. Web developers can use all these events to build up their web application in a dynamic way.


After compared the version between 1.x and 2.0. 1.x is unable to open a particular page not inside the project but 2.0 can modify particular page without open the entire project. We can know that the code behind pages is a efficiency way to write all the functions, logic to make the web development process become more efficiency and effectiveness. As the conclusion, 2.0 has added more features to increase the performance and the secure of data. (Benoy Baskaran. 2006). 3.0 compared with ASP.NET 3.5

The 3.0 is using a base of the 2.0 but there are added several of the new features on it such as Windows Presentation Foundation (WPF), Windows Communication Foundation (WCF), Windows Workflow Foundation (WF) and Windows CardSpace (WCS).

First of all, The Windows Presentation Foundation is one of the interface sub-system using at windows. Windows Presentation Foundation has using the Windows function like create, view and manage of the files, media and user interface (UI). Because it will make the web developers can create the more attractive, better impression on the interface and the different use experience on it. Windows Presentation Foundation (WPF) is built with 2 important parts which is display engine and the framework. The mainly function is to build the 3D graphic and use the Direct3D technology.

Next, Windows Communication Foundation (WCF) or name as Indigo. It is a service-oriented communication system. It has all the current .Net features like .Net remoting, ASMX,WSE and MSMQ. The WCF is built on the version of the .net Framework 2.0 and above. It also is a core of the Windows Vista. Windows XP and Windows Server 2003 operating system also support once install the WinFX Runtime Components.

Besides, Windows Workflow Foundation is the next features on the 3.0. It is a new workflow development on the .net Framework. Windows Workflow Foundation include the namespace, workflow engine for Visual Studio 2005. It support in Windows XP, vista and Windows server 2003 as well.

Lastly, Windows CardSpace (WCS) is an application that stored the user information in a more secure way and in digital form. It has provide a unify interface to select which identity need to use for transaction. For example, use an identity to login to a specify website. As the conclusion of 3.0 is a combination of 2.0 and Windows Presentation Foundation (WPF), Windows Communication Foundation (WCF), Windows Workflow Foundation (WF) and Windows CardSpace (WCS). (Mnaveenrao. 2009).

What is new in 3.5

After we view the new features of 3.0, let us see what other new features that will be added in 3.5. 3.5 is implementing inside the Visual Studio 2008 and it released on year 2007. The 3.5 is using the same engine in the 3.0 and it has added new features in it. So, let check out what are the new features in 3.5.

First of all, one of the new features that added inside the 3.5 is the AJAX. Although 2.0 can use the features of the AJAX, it still needs to install the extension to 2.0 and 3.0 only can successfully use the features. It is totally different which AJAX is integrated in 3.5. So, it is help web developers to build a better quality user interface easily. (Suprotim Agarwal. 2009)

Next features that added in the 3.5 is LINQ. LINQ (Language-Integrated Query) is to display the query that capability to the programming language such as C# and The format of query in LINQ is something like the format of SQL. It is contains Select, From and Where keywords which have the same functions in the SQL. Here is the example of LINQ.

Int Rental = from house in Rent

where rental > 100

select house; AJAX have added several new controls that can easily to call a control that can link to the datasource. The first new control is called ListView. ListView control is consist of some of the features like can show the result of the datasource in different view such as Datagrid, Gridview, repeater and the controls that available in 3.0. It allows web developers have the ability to insert data, edit data, delete data, sorting the data. These controls are flexible because the web developers can design how the data present the result.

After view the features of AJAX, 3.5 is added few new assemblies like System.Core.dll, System.Data.Linq.dll and System.xml.Linq.dll is an assembly to implementation for LINQ. System.Web.Extensions.dll is the implementation for AJAX. 3.5 allow different version of store on the same computer.

Security in

Securing an ASP.NET application requires a clear understanding of all the security options provided in ASP.NET, and how all the various security subsystems interact.

And since ASP.NET is built on the Microsoft .NET Framework, the ASP.NET application developer also has access to all of the built-in security features of the .NET Framework, such as code access security and role-based user-access security. It is imperative to understand how the various security subsystems interact, to be able to secure your ASP.NET application effectively.

Basically, to enable security for an ASP.NET application, you need to configure the application to implement, at the very least, the two fundamental functionalities described in the following table.

Security function



The process of obtaining identification credentials from a user ( such as name and password ), and validating those credentials against some authority.


The process of controlling access to resources based on the authenticated identification credentials ( such as role ).

ASP.NET implements authentication through authentication providers, the modules that contain the code to authenticate user credentials. ASP.NET includes the following authentication providers. To enable authentication for an ASP.NET application, you need to create an authentication section entry in the application root configuration file. The common syntax for the authentication section is as below:

Using ASP.NET Configuration Files

ASP.NET configuration has a hierarchical architecture. All configuration information for ASP.NET is contained in files named Web.config and Machine.config. Web.config can be placed in the same directories as the application files. The Machine.config file is in the Config directory of the install root. Subdirectories inherit a directory's settings unless overridden by a Web.config file in the subdirectory. In a Web.config file, there are sections for each major category of ASP.NET functionality.

The security section of a Web.config file is organized as follows:

There are three major subsections: authentication, authorization, and identity. The values for each of the elements are usually set by overriding this section of the computer-level configuration file with a similar section in an application configuration file placed in the application root. All subdirectories automatically inherit those settings. However, subdirectories can have their own configuration files that override other settings. Besides, You can use the <location></location> tags to specify a particular file or directory.

Case Study on PHP

After the evaluation of the, we can know that there are a lot of changes and improvement that involve in the latest version. But there are still got competitor in the web development field. There are still got another language and platform to let web developers to choose their favorite web development tools to build their web application. One of the competitors for is PHP.

Introduction of PHP

PHP is stands for Hypertext Preprocessor. PHP is open source language and it is a cross-platform because it compatibility with different operating system such as Windows, Unix system. PHP is a scripting language to build dynamic web site and it is run at the server-side. The PHP syntax is similar with the language of C, Java and Perl. So, it will help web developers build their web application efficiency and quickly. PHP allows web developer write the simple PHP syntax in HTML files directly, it can done this by eliminating the need of cgi programs. Moreover, PHP make web developers easy to supervise to the large web application by put all the components inside one html file.

For example, when creating the catalogue for online trading web site, the web developers must have to design all the design templates for all the catalogues web pages. In the early day, the web page design is written in the html format and shows all the data by using different type of design templates. In PHP, is only need one application to build all the web application pages that link to the database in the appropriate pages, correct location and related content. This is to avoid any redundancy web pages is created and easy to maintain and manage the web application.

As we know, PHP is a cross-platform scripting language. So, we not only can use the PHP code to build web application, but it can use all the PHP libraries and all the code written in PHP. One of the big features in PHP is it supports for numerous databases such as Oracle, MSSQL, MS Access and others. Besides, it is support networking, zip and consist a set of built-in functions. IT is free to download from the PHP website by everyone. PHP is a language easy to learn because most of syntax is similar to language C.

In my opinion, I think that performance is higher than PHP. That is why I choose as the web development tool in my project. application is developed using Visual Studio which produced by Microsoft. It is easy to build the web application interface and component easily added in the web application. It makes the coding part for the web application is much simpler and development more productivity.

Although PHP is an open source scripting language for all the web developers, it does not have own web development tool to build their web application. They need to use third party software to implement their PHP concept and coding inside. Some of the third party software like Adobe Dreamweaver is one of the software that can write PHP scripting language. Although there are free to charge in use of PHP scripting language, but some of the third party software may need to buy license to continue use for web development. So, it also needs to cause the cost of web development increased.

Besides, Visual Studio .NET is provides a huge of features to make the web development easier. Web developers also provide students to download a free scaled down Visual Studio version which can provide better features.

The features that come with the PHP is lesser and it was very simple features that use to build web application. It will make web developers have the limitation to build their web application. However, there are a lot of add-ons which available on the internet for web developers to download. With the PHP add-ons, it will make the PHP has some same function inside the Visual Studio. It is very troublesome to ask PHP web developers download the add-ons one by one and implement to PHP. It will waste a lot of efforts and time to download and install the add-ons. . For example, AJAX is not built in in PHP, web developers need to download themselves. So, is better than PHP which the Visual Studio will come with a full set of the features that need to use in web development. It will make the web development process running smoothly and more productivity.

On the other hand, Jasir Javaz (2010) noted that PHP getting a huge support from the web developers. This is because the PHP is an open source and it is free to everyone. Besides, PHP version 5 has provide many object oriented development concepts to the web developers to build their web application in a better way. It will make the structure of the web application and the coding is easy to implement each other's. In, it is different with PHP which is has better languages support. able to let different language background web developers use Visual Studio.Net to build their own web application. The supported languages for got, C#, J#, C++, COBAL.

PHP is run on Apache server and Apache also is an open source. is run on IIS which is Internet Information Services. The benefits of using are the user interface design and application coding part is separated to 2 parts. So, it is easy to let web developers to focus on design the overall web application interface. Besides, the code-behind pages also easy to manage and update if there have any changes or any new logic need to implement in it. So, is more user friendly in use to design a web application design. This is one the reason I choose in my project. It is not only provide more features and it is easy to let me design the web application interface and easy to manage and update.

As the conclusion, there are a lot of factors and reasons to make a web developer choose their own web development tool. A web developer chooses the suitable web application tools will make their more understanding on the application and use specialize programming language.


PHP is an open source and free to everyone. PHP also work on Linux OS which is open source as well. Using Linux OS, the performance will be higher, more secure than using Windows. It is low cost for whole web development. PHP is easy to learn especially for the beginners because the scripting language is similar to language C. is an powerful which full set of the features that easy to build up an efficiency and effectiveness web application. is using the pre-compiled concept which I have mentioned above. Better programming language support and easy design for user interface and code-behind.


As the conclusion, I found out that is one of the best web development platforms to build a web application. has provide different type of the features to make pages become more flexible, easy to maintain and easy to update. allows you to code your web application in two different places which is user interface layer and the web application layer. The web developer can done the web application interface at the user interface layer and code it in web application layer (code-behind pages). The structure of the can make the web application become flexible, scalable and easy to maintain.

Moreover, is also offers different type of the programming languages can be used to build the web application. The more languages that support for the, there are let different background of the web developers can working together without using different version of the Operating Systems. It also supports Object-oriented structure programming. is

ASP.NET Server Controls

The server control provided by has the similar functions to Windows controls. There are allows to create new server control, customized the server control directly in the web application. Besides, Windows server also provides a more secure for the web application. It also allows to use other features available in the like authentication or authorization to make the web application security become stronger. With the server controls, it can build more user friendly web application.

On the other hand, is integrated inside the which to allows the web application access to the database. Visual Studio .Net also provides the database design tools to let web developers use the appropriate view for the database. Visual Studio .Net not only support for, HTML coding, but is also fully support the XML (Extensible Markup Language) coding and the CSS (Cascading Style Sheets).
