QUERY: variable scope in ASP pages?

[John]

Hi all,
Can anyone tell me if its possible when using ASP pages, to define a
variable which is available to ALL asp pages in the site?

Would I need to use a 'global.asa' file, and if so, how do I define
the variable in it, and then reference it in other asp pages.

TIA.

Would a session variable work?

Hi John,

To all visitor sessions or global to all pages used within a visitors session?

Hi,
You can set an application variable which is the same for all users
application("Whatever") = "something"
or to have the variable different for each user
session("whatever")="something"

It would have to be the latter.

Where would that application variable be set?....in a global.asa file?
Also, I'm not 100% certain what constitutes an application in the web
sense?
Also, if an application variable is set this way, would I be able to
change its value in other pages?
TIA.

John,

An application is a group of asp pages working together
Application variables are created in the global.asa file.
An application is a group of asp pages working together
Application variables are global and affect all users
Application variables can either last for a session or as
long as the application is running.

A Session occurs when a new user accesses an asp page
Session variables can be created in either the gloabl.asa
file or in any asp page
Session variables can be changed in any asp page
Session variables affect only the one user
A Session ends when the user navigates out of the
application and the timeout expires- default is 20 minutes

Thanks Mike,
I think thats cleared it up a bit for me.

Consider using an ASP include page w/ global variables on all pages instead of editing global.asa
- any changes to your db will probably redo your global.asa and you may lose your edits

Hi John,

You can set or change an application variable anywhere you like - just as
you would any variable. However in most cases you would set it in
global.asa, it lasts from when the server is booted up until either the
server is re-booted/shut down or you change any pages in the app. You'd
probably want to set the variable when the application starts which you'd do
in global.asa like this
sub application_onstart
application("whatever") = "something"
end sub
