The Server Object
The Server object makes us available the methods and properties of our server ( IIS ).

Syntax

Server.property|method

Properties

Description

ScriptTimeout

An integer which specifies time in seconds until which the script can run after that the server aborts the script and displays an error message.

Methods

Description

CreateObject	Creates an instance of the object ( a component, application or a scripting object ). The component can be instantiated by giving its CLSID or ProgID in the Server.CreateObject method e.g. Server.CreateObject ("MSWC.MyInfo").
Execute	Executes the given .asp page and then returns the control to the page who called the method. Very useful method which can be used to execute another .asp page without leaving the current page and then control is passed back to the calling page.
GetLastError	Returns an ASPError object which can be used to get information about the last error occured in the ASP script.
HTMLEncode	Provides HTML encoding to a given string. All non-legal HTML characters are converted to their equivalent HTML entity e.g. "<" is converted to < .
MapPath	Maps the specified virtual or relative path into physical path of the server.
Transfer	Transfers the control of the page to another page specified in the URL. Note that unlike Execute, control of the page is not returned to the page calling the Server.Transfer method.
URLEncode	Provides URL encoding to a given string e.g. Server.URLEncode ("http://www.stardeveloper.com") returns `http%3A%2F%2Fwww%2Estardeveloper%2Ecom.`

The Session Object
The Session object is automatically created every time client browser access pages from your web site. Session object is specific for every user and varies from user to user. It can be used to store variables specific for a user and IIS will maintain these variables when the client moves across pages within your site. You can create and access Session scope variables. You can store user specific preferences within Session object such as 'font-size, background-color' etc.

Note that scripts for different Events are to be declared in global.asa file.

Syntax

Session.collection|property|method

Collections

Description

Contents	Contains all the items which have been added to the Session object. You can iterate through the Contents collection and retrieve a list of all the items added or you can retrieve a specific item. Note that it contains all the Session items except the ones created using <object> element.
StaticObjects	Contains all the items which have Session scope created using <object> element. As with Session.Contents collection you can iterate through the StaticObjects collection to get a list of items or you can get a specific item out of the StaticObjects collection.

Properties

Description

CodePage	An integer which defines the code page to be used to display content to the client browser e.g. code page 1252 is used to for American english and most European languages and 932 is used for Japanese kanji.
LCID	Stands for locale identifier. It is a standard international abbreviation that uniquely identifies the locale e.g. LCID 2057 stands for British locale.
SessionID	A long which returns the session identifier for this client browser.
Timeout	An integer which specifies a time out period in minutes. If the client doesn't refresh or request any page of your site within this time out period then the server ends the current session. If you do not specify any time out period then by default time out period is 20 minutes.
