Sun 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. This section discusses the following ASP built-in objects:
ASP Built-in Object |
Description |
Stores information (variables and objects) needed for all users of a particular application. Information stored in the Application object persists for the lifetime of the application. | |
Provides access to values passed to the server by the client. | |
Controls the output from an ASP script to the requesting client. | |
Provides access to methods and properties on the server. These methods and properties typically serve as utility functions. | |
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 development 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. By using the built-in Session object, an application (or object) can handle session management tasks.
Note
ASP scripts provided in the examples are assumed to be enclosed in script delimiters. The <%, %>, <SCRIPT>, and </SCRIPT> delimiters are generally not shown.
