Active Server Pages
(ASP) is Microsoft's server-side script engine for
dynamically-generated web pages. It is marketed as an
add-on to Internet Information Services (IIS).
Programming ASP websites is made easier by various
built-in objects. Each object corresponds to a group of
frequently-used functionality useful 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 maintains 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 <script
language="language" runat="server"> syntax. JScript
(Microsoft's implementation of ECMAScript) is the other
language that is usually available. PerlScript (a
derivative of Perl) and others are available as
third-party installable Active Scripting engines.
InstantASP and ChiliASP are technologies that run ASP
without Windows Operating System. There are large open
source communities on the WWW, such as ASPNuke, which
produce ASP scripts, components and applications to be
used for free under certain license terms. |
