What is ASP.NET?

ASP.NET is .........

  • ASP stands for Active Server Pages
  • ASP.NET is a server side technology that built on the .NET technology from
  • ASP.NET files use the extension ".aspx" to activate the supported web server to compile the ASP.NET files
  • ASP.NET also uses delimiters "<%" and "%>" as markup tags to specify the beginning and end of the enclosed script commands.
  • ASP.NET also supports Embedded code blocks in Web Forms pages for providing backward compatibility with ASP technology.


Examples of ASP.NET code

ASP.NET Code Input:
<% Response.Write ("<h1>This is a Sample ASP.NET Code</h1>") %>
HTML Web Page Embedded Output:

ASP.Net Technology

Unlike ASP technolgy, ASP.NET compile the ASP.NET document and return a HTTP document. In other words, ASP.NET technology adds an abstraction layer on top of HTTP to handle ASP.NET files and the web server becomes operating in a two-tiered way.


ASP.NET Document

Basic Features of ASP.NET files.........

  • ASP.NET file is a HTML script with extension ".aspx" to describe web page
  • ASP.NET file is just a HTML script containing ASP.NET scripts.
  • ASP.NET technology is just an additional script compiling engine to compile the ASP.NET file and return a HTML document.
  • HTML document contains HTML tags and plain text without script command can also be an ASP.NET file by renaming the extension to ".aspx"
  • ASP.NET technology also enables both ActiveX scripts and ActiveX server components running on the server through the .NET technology.


Examples of ASP.NET page

HTML Document Input:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "">
        <title>Sample Page</title>
        <meta http-equiv="Content-Type" content="text/html;charset=utf-8"> 
        <% Response.Write ("<h1>This is a Sample ASP.NET Page</h1>") %>
HTML Web Page Embedded Output:

ASP.NET Element

Unlike ASP document, code and page layout are seperated into two sections. In general, ASP.NET document can be divided into three parts.

  •  Directive block: used by ASP.NET engine as settings for the compilers to process ASP.NET document.
  • Script block: used by ASP.NET engine as programming code for generating the HTML document.
  • Form; used by ASP.NET engine as document layout for generating the HTML document.

ASP.NET Mechanism

In general, the mechanism of ASP.NET engine in the IIS is similar to a HTML compiler for ASP.NET file.
