ASP Built-in Objects

Chili!Soft ASP provides five built-in or intrinsic objects for the Active Server Pages (ASP) framework: Request, Response, Application, Server, and Session. Built-in objects are objects that are included on all ASP pages, they do not need to be created before they can be used. The following table summarizes the built-in objects:
 

Built-in Object Description
Application
 
Stores information (variables and objects) needed for all users of a particular application. Information stored in the Application object persist for the lifetime of the application.
 
Request
 
Provides access to values passed to the server by the client.
 
Response
 
Controls the output from an ASP script to the requesting client.
 
Server
 
Provides access to methods and properties on the server. These methods and properties typically serve as utility functions.
 
Session
 
Stores information (variables and objects) needed for a particular user session. Information stored in the Session object is not discarded when the user jumps between pages in the application, instead information persists for the entire user session.
 
Built-in objects simplify programming tasks by solving web protocol programming issues. For example, built-in objects can provide mechanisms to process data sent using the HyperText Transfer Protocol (HTTP). HTTP is a stateless technology and the server cannot track the location of users in an application or the use of an application. Using the built-in Session object an application (or object) can handle session management tasks.
 

Note:

Examples of ASP scripts in the examples which follow are assumed to be enclosed in script delimiters. The <%, %>, <SCRIPT>, and </SCRIPT> delimiters are generally not shown.
