What is Classic ASP?
ASP (Active Server Pages) or also known as Classic ASP is Microsoft’s server side script engine for dynamically generated web pages. It is released as an add-on to Internet Information Services using in the Windows NT 4.0 option pack.
Using a server-side scripting language we can manage the content of any webpage so dynamic code of the browser can be generated depending on various conditions that we set in our ASP program.
ASP is an older version of ASP.NET, therefore ASP.NET is a more improved version of it. But most people still prefer ASP. Here are some of the reasons that ASP is an advantage.
Although there are a magnitude of advantage to what ASP.NET offers compared to classic ASP, still the classic has something for the competition:
Includes don’t works as expected in ASP.NET. Migrating from classing ASP to ASP.NET is a pain because of .NET.
ASP.NET won’t permit you to go beyond the root folder of the application.
Unlike ASP.NET classic ASP Hosting runs under the IIS process space or popularly known as the inetinfo.exe.
ASP has a script block that is marked as runat=server. This block contain functions that allow us to include executable code outside the scope of the function. ASP.NET doesn’t allow this to happen, instead it uses a different, and more complicated method.
Another thing that complicates the use of ASP.NET is that you will have to adapt to newer methods therefore you will need to learn how to do certain work in .NET. Which means that apart from your knowledge in ASP, you need to understand how .NET works. This makes a simple task more complicated than it was compared to classic ASP hosting.
So ASP is best as a learning tool for inexperienced beginners. Compared to ASP.NET everything will work right out-of-the-box and much simpler to code.
What is its advantage in web hosting?
ASP and ASP.NET both have the performance, scalability and stability when it comes to web hosting. You can’t find any difference in speed and performance on both of it. The hard part is shifting to ASP.NET because ASP.NET is new, there are certain codes and functions in ASP that just became obsolete.
Should I Migrate To ASP.NET?
should we move to asp.net
Migrating from ASP to ASP.NET is not as easy as it sounds. The first thing that you want to keep in mind is the introduction of .NET in ASP. If you are new at this then there are so many things that you need to learn first before you can successfully migrate to ASP.NET.
And along with that, here are some things to consider:
The good news is ASP is ASP.NET compatible. You can shift to ASP.NET with ease.
Both ASP and ASP.NET applications can run side by side on a server without affecting the performance of each other. This happens because ASP.NET has a new file extension (.aspx) and a different configuration model used between two tecnologies. So these two systems run in separate processing engines.
There are several changes in ASP.NET that you might not get used to at first but will be helpful once you are familiar with it. These are:
API changes. Core API of ASP consist of intrinsic objects, ASP.NET has a newer approach to it.
Structural changes. The layout and coding style is different, if you want more support for other programming language, use ASP.NET. But VBScript and Microsoft’s JScript works better in all aspects so why change it?
Application Configuration. In ASP, all configuration information is stored in the system registry and in IIS. If you are used to this old way of configuring things then you may find it hard to administer a new configuration based model that is based in XML.
Now you understand the reason why asp hosting still has an advantage over ASP.NET. Make sure you can adapt to changes quickly before making that shift.
