What Are Active Server Pages?
Active Server Pages (ASP) were introduced by Microsoft as an application to make web site pages dynamic. In essence, ASP is a server-side scripting language like PHP but it cannot work on platforms that are not Microsoft supported.
With ASP usage to make pages in a web site more dynamic, web developers can offer a smoother overall look to the web site while also making each page have a higher level of user interaction. Overall, using Active Server Pages can offer both the end-users and web developers a way to create dynamic and driven web pages.
