ASP stands for Active Server Page. ASP was developed by Microsoft to allow programmers to create a dynamic website. It is the first server side script engine and now has been superseded by ASP.NET. ASP is an HTML page that includes one or more scripts. Scripts are processed by an ASP interpreter on a web server by using input requested for a page to access data from a database before delivering it to the receiver.
File Extension: .asp (for ASP)
File Extension: .aspx (for ASP.NET)
ASP is a feature of Microsoft Internet Information Server (IIS), but as it handles HTML page, it is supported by all browsers. You can create an ASP file by including Jscript or VBScript in an HTML file.
