Active Server Pages (ASP)

Active Server Pages abbreviated as ASP is Microsoft's server-side script engine for dynamically-generated web pages. It is marketed as an add-on feature to Internet Information Services. Programming ASP websites is made simpler by various built-in objects. Each object corresponds to a group of frequently-used functionality helpful for creating dynamic web pages. In ASP 2.0 there are six such built-in objects: Application, ASPError, Request, Response, Server, and Session. Session, for example, is a cookie-based session object that retains variables from page to page.

Most ASP pages are written in VBScript, but any other Active Scripting engine can be selected instead by using the @Language directive or the syntax. JScript is the other language that is usually available. PerlScript and others are available as third-party installable Active Scripting engines.

InstantASP and ChiliASP are technologies that run ASP devoid of Windows Operating System. There are large open source communities on the WWW, such as ASPNuke, which creates ASP scripts, components and applications to be used for free under certain license terms.

Active Server Pages abbreviated as ASP, a requirement for a dynamically created Web page with a .ASP extension that utilizes ActiveX scripting -- typically VB Script or Jscript code. When a browser desires an ASP, the Web server creates a page with HTML code and sends it back to the browser. So ASPs are like CGI scripts, but they enable Visual Basic programmers to work with familiar tools.

Application Service Provider is also abbreviated as ASP, a third-party entity that manages and distributes software-based services and solutions to customers across a wide area network from a central data center.

An application service provider (ASP) is a business that offers computer-based services to customers over a network. Software provided using an ASP model is also sometimes called On-demand software or software as a service. The most limited sense of this business is that of offering access to a particular application program (such as medical billing) using a standard protocol such as HTTP.

The need for ASPs has evolved from the increasing costs of specialized software that have far surpassed the price range of small to medium sized businesses. As well, the growing difficulties of software have led to huge costs in distributing the software to end-users. Through ASPs, the complexity and costs of such software can be reduced.

There are numerous forms of ASP business. These are a specialist or functional ASP delivers single application, such as credit card payment processing or timesheet services; a vertical market ASP delivers a solution package for a specific customer type, such as a dental practice; an enterprise ASP delivers broad spectrum solutions; a local ASP delivers small business services within a limited area.

Rising technology gives familiarity to Active server pages, which is shortly named as (Asp). Dynamic and creative pages are made through this technology and active server pages made use of the server side scripting that are not pretentious by the type of browser the internet visitor is operational. You can use VBScript in the default scripting language in which is used for writing ASP. Few other languages like JavaScript can also be used for writing Active server pages (Asp).
Active server pages (Asp) have the extension as .asp. It is difficult to view the pages of ASP in web page in the browser. It is termed as Active server pages because all the request and demand through server. When browser requests a web page with the extension .asp the server identifies to understand and interpret several ASP enclosed within he web pages. It previously sends html created to the web browser. This is how all the active server pages conceded the web browser. Active server pages guarantees about toil with any web browser functions. This is also regarded as server side technology.
Microsoft launched Active server pages on it server and established it as a web based designing language. Internet information services (IIS) that executes on windows 2000 or windows XP Pro/NT4. These are web servers were the ASP pages runs and executed. Microsoft IIS is installed before working with Active server pages on any personal computer using windows. People are very curious about this language. You will not to spend any money on the installation of Internet Information Services and PWS (Personal Web Server).
Following gives places for IIS and PWS for windows users
Windows XP Home Edition – This Operating System does not supports IIS and PWS.
Windows 98 – “add-ons” is the personal web server found in windows 98 CD.
Windows NT4/95 – NT4 option can be used to embraced IIS through downloading.
Windows 2000/XP – Add or Remove in Control Panel can visualize internet information services.
Asp file is demanded or requested by web browsers then an internet information service passes the request to ASP engine. Then line-by-line interpretation of the asp files and executed. Asp file is revised to browse as simple html language. Asp permits any modification, amendment or inserting any content in the dynamic web page. The major features and advantages in asp is that it acts as an alternative of PERL and CGI is effortlessness and speed. Asp code is not visualized and observed that makes the asp programmer the best safety and security reasons. Well when used it reduced the network traffic for asp programmers.
