ASP Application Object

[MEM]

Hello,

I'm using application variables for a web based sales tracking
application. I use the variables for stuff like connection string,
database name, etc. I store the values in a asp file that is included
in a login page. The assignments are in a routine/procedure that I
then call on the login page. This is done everytime a user connects to
the login page.

So, what's happening to the variables? Are they being overwritten
everytime a user accesses the page? I'm not checking for the existence
of the variables. I just call the routine everytime the page is
accessed. I know the values are shared for all users but, I was
wondering if I should check for the existence of the variables? Will
it free up resources? Should I be using locks?

Thanks.

Yes, they are probably being overwritten. Is there any reason you're not
creating the variables in Application_OnStart in a global.asa file?

I think you are confusing application and session. Sessions survive the
lifetime of a user connected to the application. The application outlasts
user sessions. It would make more sense, as Ray suggests, to populate these
variables in application_onstart.

What's the benefits of using the global.asa file versus an asp
include? Also, when creating the application folder in IIS, does it
automatically create a global.asa file?

benefits vs an include? well, they're two different animals, but basically a
global.asa runs at the start of the session and the start of an application,
so it's the logical place to set app and session variables which don't
depend on some sort of user input.

no, a global.asa is not created automatically by IIS, but may be created by
your editor, depending on what you use
