Course Overview Today, users expect the web environment to be responsive and interactive. Active Server Pages (ASP) is a Microsoft server-based technology for building dynamic and interactive Web applications. ASP provides a powerful development environment for creating Web applications. Through its object model it exposes core functionality needed by any Web programmer.Visual Basic Script (VBScript) is an extended subset of the Visual Basic programming language. This course will use VBScript when developing ASP applications.The course will take ASP novices and introduce them to this powerful framework, before looking into the ASP object models and development techniques. Creating sophisticated web pages and data-driven applications with ASP, as well as performance and security, will be covered. The course is made up of a mixture of lectures and hands-on exercises. There are separate practical sessions for each technical chapter which reinforce the theory and techniques covered in the course Course Outline Web Application Development - Static HTML pages
