.ASP File Extension

Server-generated Web page that may contain scripts written in VBScript, C#, or JavaScript; parsed on the server, which generates HTML that is sent to the client's browser; commonly used by ASP.NET sites and websites hosted on Microsoft IIS-based servers.

Since ASP pages are processed on the server, website visitors do not see the actual ASP code, just the HTML generated from the scripts within the page. ASP pages typically use the ".asp" extension rather than ".html."
