Knowledge Base Articles » KB100202: Controlling Web Applications Using the global.asa File.
The global.asa file is a script file that is associated with each Web Application
on the Web server. A Web Application is a collection of ASP and HTML pages
all contained within a folder on the server. However, not all folders on
the Web server are Web Applications.
To determine whether or not a folder is a Web Application, view the properties
for the folder in Internet Service Manager on Windows NT. In the "Application
Settings" portion of the window, if the "Configuration" button is greyed
out, the folder is not a Web Application (you can click the "Create" button
to make it a Web Application if you choose). However, if the "Configuration"
button is enabled, and there is a "Remove" button above it, then the folder
is already a Web Application.
The global.asa file resides in the root folder of a Web Application and
is run each time the Application is started or stopped. It is also run each
time an individual user starts or ends a browser session that accesses the
Application's Web pages.
The global.asa file is therefore used to execute code, initialize variables,
connect to databases, or perform any other tasks that need to happen only
at the start or end of an Application or Session. This is done by implementing
event handlers. You can find examples of implementing these event
handlers in the ASP subdirectory of the DevGuru Technologies
