Classic ASP uses the server-side scripting language to develop the Web pages irrespective of the browser you are using. Classis Asp was released in January 2002 and was superseded as ASP. Later on ASP.NET was known as Classic ASP or ASP Classic. ASP is the server-side script engine that is used to dynamically generate Web pages online.
VBScript is considered as the default scripting language required to develop ASP web pages. You can also use the other scripting language, such as JScript. The classic ASP page is saved with the extension .asp instead of .htm. When the page is requested by the Web server, it is then interpreted before producing the response to the browser.
The reasons why to prefer Classic ASP are given below:
- Ease of Use: Using Classic ASP you can develop plain HTML pages in which the ASP code is embedded within tags. You simply need to place the ASP files within a directory on the server and execute the pages. In case of making any change, you simply need to edit the .asp files and save the changes.
- Language independence: Allows you to develop the applications virtually in any language. The two languages available by default are VBScript and JScript. This allows the ASP developers to use the programming experience. If you have worked once in VBA, then you will not have any problem working with the languages.
- Short Learning Curve: You can utilize your current programming skills and can jump into ASP in short time, provided you are aware of HTML.
Initially, the three versions of ASP were released, namely, ASP 1.0, ASP 2.0, and ASP 3.0. These versions were introduced with different versions of IIS. The ASP 1.0 was released on December 1996, ASP 2.0 was released on September 1997, and ASP 3.0 was released on November 2000. Various new features were introduced with the release of each version of ASP.
There is not much of difference between ASP 3.0 and ASP 2.0. However, there are some additional features, such as Server Transfer, server execute method, and many more. ASP is still supported till 14th January 2020.
