Classic ASP vs. ASP.NET


Is ASP.NET better that Classic ASP?

ASP is a server-side scripting engine known for its dynamic generation of web pages. The script mainly written in VBScript, JScript or PerlScript, is interpreted server-side and then sent to the client-side browser for rendering. ASP.NET on the other hand is a powerful programming framework consisting of many object-oriented languages, class libraries and Common Language Runtime. The application developed in ASP.NET can have configurable components, integration to multiple data sources and user interfaces.

Given the power, scalability and overall better application design techniques available via ASP.NET, it’s hard to presume why a developer or business would continue to use Classic ASP. Most modern code will be written in C# using ASP.NET components and features. Migrating from ASP to ASP.NET requires developing an approach that analyzes all the layers of the application.

Difference between ASP and ASPx

There are four main areas that make ASP.NET a much better choice as an enterprise application development framework.

Application stability

ASP is susceptible to application crashes, due to its processes as IIS needs to be paused or restarted regularly. ASP.NET process is separate from its process spaces, which avoid application crashes and ensures a stable application.

Server-side execution

Classic ASP is comprised of VBScript or JavaScript and each page is executed at run-time. This line-by-line overhead drives down the performance.

On the other hand, ASP.NET compiles the code the first time it is accessed and the compiled code results in .NET classes housed within assemblies. This allows subsequent page requests to be serviced with previously compiled code. Therefore, ASP.NET inherently delivers a far more secure and efficient rendering model and improved user experience.

Scalability with zero downtime

With Classic ASP applications, page components are difficult to update, maintain, or replace. Updating a component requires shutting down of the process space, replacing the component and restarting the IIS. This means application downtime.

ASP.NET comes with its built-in capabilities to perform scalable and efficient updates without application downtime. .NET deployment model enables replacement of pages and components by directly changing the code without restarting the web server. The infrastructure accounts for the change the next time a request is made to that altered page or component. Therefore content updates, fixes, and enhancements in an ASP.NET application can be made with little to no impact to the user base.

Scripting support

ASP.NET supports server-side programming and scripting languages. Unfortunately, Classic ASP only supports VBScript and JavaScript. C# and VB.NET become instantly accessible to developers within ASP.NET. Furthermore, the .NET class libraries are invoked within the same application. This gives ASP.NET developers complete control and flexibility over building limitless functionality and user experience.

ASP.NET makes development of robust, rich applications possible with deep programmatic support.
