What is the difference between asp and aspx

The main differences between ASP and ASPX are: the file extensions are .asp and .aspx respectively; the programming languages ​​are different, ASP supports VBScript and JScript, while ASPX only supports C# and Visual Basic .NET; the code embedding method is also Different, ASP uses <% %>, ASPX uses <script runat="server"> and <% %>; ASPX code is compiled on the server, with higher performance and security; in addition, ASPX Supports the use of .NET components and has better maintainability.

The difference between ASP and ASPX

ASP (Active Server Pages) and ASPX (Active Server Pages Extended) both It is a server-side scripting technology developed by Microsoft for creating dynamic Web pages. There are several key differences between them:

1. File extension

ASP pages use the .asp extension, while ASPX pages Use the .aspx extension.

2. Programming Language

ASP supports two programming languages: VBScript and JScript (a variant of JavaScript). ASPX, on the other hand, only supports C# and Visual Basic .NET.

3. Code embedding

ASP uses the <% %> tag to embed code into HTML, while ASPX uses <script runat="server"> and <% %> tags.

4. Compilation

ASP code is executed in the client browser, while ASPX code is compiled into intermediate language (IL) on the server. This makes ASPX code run faster and be more secure.

5. Component Support

ASPX supports the use of .NET components, which makes it easier to create complex web applications.

6. Performance

ASPX usually performs better than ASP because it is compiled and executed.

7. Security

ASPX is more secure than ASP due to its compilation mechanism.

8. Maintenance

ASPX code is easier to maintain and debug because it uses a strongly typed language.

Summary

ASP and ASPX are both server-side scripting technologies, but ASPX has faster performance, higher security, better component support and The ability to use C# and Visual Basic .NET becomes a more modern, advanced choice for developing dynamic Web applications.
